Double Oscar-winning composer A.R. Rahman Friday said that his son Ameen might sing in filmmaker Mani Ratnam's yet-untitled upcoming bilingual project. Ameen, 12, has already crooned the song "NaNa" from "Couple's Retreat". "A lot of filmmakers want Ameen to act, but I want him to concentrate on studying. He might sing in Mani Ratnam's next film," Rahman said at an event. He was talking about his upcoming concert on Oct 2 for a Tamil news channel. Rahman will perform 50 Tamil songs at the concert, for which he's been preparing for nearly "two months". The Mozart of Madras will be accompanied by students from his music college KM Conservatory along with singers such as Blaaze and Karthik at the concert. (Source: IANS)
