sing the theme song,’’ says Sargam of the mid-tempo track called Khamoshi Mein Pukar Hain with lyrics by Mehboob. The English version has been rendered by Korean vocalist Jolin Tsai.

Rahman says the entire score was written in three days. ‘‘It was first meant to be a collaborative effort with the Beijing Philharmonic, but was cancelled due to the SARS outbreak,’’ he says, ‘‘But this only came as a blessing and we recorded the score in Prague with the Czech orchestra, which is one of the best in the world.’’ His Chinese links don’t end there.

He’s been recently asked to compose a track for violinist Vanesa Mae’s world album. In Mumbai, to serve yet another cause — Save The Children India (STCI, the last one being for Cancer patients) — Rahman says: ‘‘There’s family, film, social causes and spirituality. It’s tedious to do repeat the same tune.”

‘‘I’ve been donating money to the organisation for the past three years and this was a chance to actually do something,’’ he says. So come Republic Day, the city will witness a Rahman concert where none other than the Big B will recite the President’s poem. The 90-minute concert will include unreleased numbers such as One Mission and I Believe, as well as Bharat Manko from the film Roja and Maa Tujhe Salaam.
