Bollywood music enthusiasts continue to celebrate the magic of Kajra Re, one of the most iconic dance numbers in Indian cinema, from the 2005 film Bunty Aur Babli. Sung by Shankar Mahadevan, Alisha Chinai, and Javed Ali, the song instantly became a sensation and remains a staple of Bollywood playlists even today. Recently, in a podcast with Humans of Bombay’s All India Mehfil, National Award-winning singer and composer Shankar Mahadevan shared a nostalgic account of recording the track, revealing a playful yet stern warning from Amitabh Bachchan himself during the process.

Shankar Mahadevan, who has given numerous chart-topping and critically acclaimed songs to Indian cinema, including Maa from Taare Zameen Par and Mitwa, shared intimate memories from the sets and recording studio while reminiscing about Kajra Re. During the conversation, he highlighted Amitabh Bachchan’s unique blend of warmth, humor, and professionalism, offering a glimpse into the larger-than-life personality behind the legendary actor.

Shankar recalled a particularly memorable moment from the time he worked with the Kabhi Alvida Naa Kehna cast and also from the making of Rock and Roll. “I remember Bachchan sir, he was shooting Rock and Roll, and we went on the set. With my kind of weight, he lifted me because he was so happy with the song. He is just too sweet. He gave me a hug and said, ‘Kya gaana banaya hai,’” Shankar shared. The affectionate gesture reflected not only Bachchan’s enthusiasm for music but also his personal charm and approachability, qualities that have endeared him to co-stars, musicians, and fans alike over decades.

When it came to Kajra Re, Shankar revealed an amusing anecdote involving the recording process and Amitabh Bachchan’s insistence on maintaining the song’s integrity. Initially, Shankar had prepared a rough version of the song, particularly for Amitabh to dub his portions. While Javed Ali sang for Abhishek Bachchan’s parts, Shankar’s version had placeholders where Big B’s segments would go. When Shankar later met Amitabh at a function, he requested, “Sir, please come and dub your parts, we have to mix the song.”

Amitabh Bachchan, already familiar with the song after shooting the video sequence, responded in his characteristic mix of humor and seriousness. According to Shankar, Bachchan asked, “So what should I dub in that?” Shankar explained that he had already kept the parts ready for him. It was then that Amitabh, with his signature jest, warned, “No, this will be like this only. Tu usko haath lagaya toh dekhna, main tera career bigaad dunga.” Translated, this means, “If you even touch it, I’ll destroy your career.”

Shankar Mahadevan recounted that Amitabh’s statement was half jest, half protective assertion. He insisted that no one else should dub his parts and cautioned Shankar not to alter the song. This lighthearted warning reflected Big B’s deep respect for his craft, his attachment to his performances, and his desire to ensure that the artistic quality of the song remained intact. Shankar also noted that Bachchan had extended similar “blessings” during other projects, including Jhoom Barabar Jhoom, further illustrating his consistent approach to his work.

The story behind Kajra Re is integral to understanding why Amitabh Bachchan was so invested in the song. Composed by Shankar-Ehsaan-Loy and choreographed to be a visual spectacle, the track features Amitabh Bachchan, Abhishek Bachchan, and Aishwarya Rai Bachchan sharing the screen in an unprecedented ensemble. The playful dynamics between the father-son duo and Aishwarya’s electrifying presence elevated the song, transforming it into one of the most memorable musical sequences of early 2000s Bollywood.

Kajra Re’s success lies not only in its catchy composition and engaging choreography but also in the synergy between the performers and the vocalists. Shankar Mahadevan’s energetic and expressive singing brought the melody to life, complementing Alisha Chinai’s sultry tones and Javed Ali’s smooth vocal texture. Together, the trio created a sonic experience that was both innovative and rooted in traditional Indian musical sensibilities, making it a timeless hit across generations.

In his podcast, Shankar Mahadevan also highlighted Amitabh Bachchan’s generosity and warmth on set. Beyond the playful warning about the song, Bachchan’s affection and enthusiasm for music were apparent in gestures like lifting Shankar during Rock and Roll shooting—a moment that Shankar described as both surprising and heartwarming. These anecdotes offer a rare peek behind the curtain, showcasing how legendary actors like Amitabh maintain a blend of professional rigor and personal kindness, creating an environment where musicians, co-actors, and technicians feel valued and inspired.

The legacy of Kajra Re extends far beyond its initial release. Even today, the song is celebrated for its innovative integration of dance, music, and narrative storytelling. It remains a benchmark for Bollywood musical numbers, exemplifying how collaborations between actors, composers, and singers can produce work that is both popular and enduring. Amitabh Bachchan’s insistence on maintaining the song’s original essence, as Shankar recalled, likely contributed to preserving the magic that has kept the track relevant over the years.

Shankar Mahadevan’s recollections also underscore the importance of trust and collaboration in the creative process. By jokingly warning Shankar not to alter the song, Amitabh displayed his investment in the artistic output while simultaneously acknowledging the musician’s expertise. Such interactions highlight how mutual respect between actors and musicians can elevate a project, resulting in a final product that resonates with audiences both immediately and decades later.

In conclusion, the anecdote of Amitabh Bachchan warning Shankar Mahadevan with the playful, yet serious, comment “main tera career bigaad dunga” is emblematic of the larger dynamics at play during the making of Kajra Re. It captures the combination of humor, professionalism, and artistic integrity that has defined Bollywood’s golden collaborations. Shankar’s storytelling provides fans with an intimate perspective on the song’s creation, revealing the care and dedication behind one of Indian cinema’s most beloved musical moments.

Today, Kajra Re is remembered not just as a song but as a cultural milestone in Bollywood music and dance, celebrated for its infectious energy, captivating performances, and memorable vocals. The behind-the-scenes stories shared by Shankar Mahadevan remind audiences that every classic song carries with it layers of effort, collaboration, and moments of personal connection between artists. Amitabh Bachchan’s playful warning, combined with his affection and admiration for the team, remains a testament to the meticulous care and love invested in creating cinematic magic.

Even after nearly two decades, Kajra Re continues to inspire music directors, choreographers, and performers, proving that the combination of strong vocals, engaging visuals, and collaborative spirit can create a timeless piece of art. Shankar Mahadevan’s reflections offer not only nostalgia but also a deeper appreciation of the relationships and creative processes that underpin such legendary works, allowing fans to connect with the song on an even more personal and meaningful level.
