Prem Kumar Gangai Amaren (born 25 February 1979), better known as Premji, is an Indian playback singer, film composer, songwriter, actor and comedian. Son of film composer and director Gangai Amaran, he often composes rap songs in Tamil cinema and is known for his comical performances in his elder brother Venkat Prabhu's films. His stage name, Premgi, is actually a spelling error, as it is meant to be "Prem G.", (the G referring to his father's name). He is also best known for his catchphrases Enna Koduma Sir Idhu ? (What atrocity is this, sir ?) and Evvalavo Pannitom, Idha Pannamaatoma ? (We've done so much, won't we do this also ?), the former being a modified version of a famous dialogue used by Prabhu in Chandramukhi (2005).
