The publicity campaign of the upcoming Hrithik Roshan-Katrina Kaif starrer, Bang Bang, kicked off, not with its title track which was unveiled yesterday, but the peppy dance track, Tu Meri. Composer duo, Vishal Dadlani and Shekhar Ravjiani, admit that it was the film's director, Siddharth Anand, who zeroed in on this number. “And he was bang on,“ asserts Shekhar.

He remembers that their brief was to compose a dance track with Hrithik in mind. And since he is one of the best dancers in B-town it was a “happy“ challenge. “The song was composed in five minutes flat. Vishal and I were jamming on the loop and we came up with an interesting format,“ says Shekhar.

Picking up the thread of conversation Vishal adds, “The engineer, while extending the loop erred, and we got an up-down-up-down tempo which intrigued us. It was a new sound and we played it back to Siddharth who loved it, so did Hrithik. That's how Tu Meri evolved.“

Aisi kya, chali hawa, ki le gayi meri saanson ko mujhse door, Tere paas aur mujhe huaa ehsaas, tu tu tu, tu meri ri ri, main tera ra, hone laga.... The lyrics, penned by Vishal, were part of the scratch-words to hum with the tune.

“Very simple words, with an easy connect and heart-felt. Everyone fell in love with them so they were retained,“ he beams. Vishal has also sung the song. “He sang the scratch and both Siddharth and I loved it. He was the best voice for this song so there was no question of getting it dubbed by anyone else,“ Shekhar reasons.

He is all praise for the lead pair whose infectious energy combined with the power of Vishal's vocals, he says, has taken the song to another level. “Since he started out, Hrithik has done so many dance tracks. Yet he manages to bring something new to a song every time. He is constantly experimenting with technique and so much effort goes into every move,“ raves Shekhar, admitting that when he watched the visuals, he was completely bowled over by the choreography and the picturisation.

“This is our fifth film with Siddharth, after Salaam Namaste, Ta Ra Rum Pum, Bachna Ae Haseeno and Anjaana Anjaani. And in every film, he has taken our songs one step up with the picturisations. We love making music for his movies,“ Shekhar signs off.
