"A.R. Rahman is very talented. I've sung very few songs for him. I love "Jiya jale", "Khamoshiyan Gun-Guna Lagi", "O Paalan Haare" and "Luka Chuppi". Rahman and I came together for the first time for the evergreen "Jiya Jale" in Mani Ratnam's "Dil Se.." and I'm asked to sing that song at every concert that I go to."
Prasoon Joshi
"Artistes and human beings like Rahman are rare. All my work with Rahman is very special to me. Much as I enjoyed writing fun songs like "Masti ki paathshala" and "Masakalli", I cherish exploring the spiritual side of my creativity in the songs "Arziyaan" and "Zariya". May god bless him with some of the happiness that he has given us through his music."
