Oscar-winning composer A.R. Rahman, who celebrated his 46th birthday on Friday, thanked his fans across the world for their good wishes. In a video link posted on his Twitter page, Rahman said: \"Hi! This is A.R. and wishing you a very happy 2012. Thank you for all your wishes for my birthday. I won\'t be in Chennai this time, I am travelling abroad. So thank you for your kind wishes. God bless you all.\" The composer has good things to look forward in 2012. He has in his kitty several southern projects like Rana, Yohan: Adhyayam Ondru, Kochadaiyaan and Pookkadai as well as an untitled Hindi movie with Yash Chopra. For now, he is upbeat about a five-city tour of Babelsberg, a German film orchestra, that will perform orchestral interpretations of Rahman\'s film compositions. The orchestra will be joined by choir members from Rahman\'s KM Conservatory. The concert will start on January 20 in Mumbai, followed by Delhi, Chennai, Kolkata and Bengaluru.
