The film, which stars Abhishek Bachchan and Aishwarya Rai in lead roles in the Hindi version and Vikram and Aishwarya in the Tamil version, has music by Oscar winner A R Rahman. According to a post in the internet recently, a song — titled Kaadale... in the Tamil version — has been sung by the lead actress Aishwarya herself!
However, music composer Rahman has denied that any such song features in the film. “Someone’s pulling a fast one,” is all he said. All eyes are on Raavan’s music as it will be the first album with the Mani Ratnam-Rahman combination that will be out after the composer’s double delight at the Oscars for Slumdog Millionaire. Besides Raavan, A R Rahman’s current projects include Rajinikanth’s Endhiran and Sultan, Couples Retreat and Vinaithaandi Varuvaa http://timesofindia.indiatimes.com/entertainment/music/No-leak-from-Raavan-Rahman/articleshow/5102242.cms
