"I Don't Smoke (Da Reefa)", by Dee Kline, a DJ for Flex FM, has been a nationwide club favourite for a year with its: "I don't smoke cigarettes, I don't smoke cigars, I don't smoke a pipe" lyric.
Dee Kline's tune was heard by Dan Tetsell in March while shopping in central London. Mr Tetsell, 25, from Stoke Newington, north-east London, noted the voice of stand-up comedian Marcus Brigstocke intoning: "Do you smoke, Paul?"
After making inquiries he discovered his line, from a sketch originally performed in 1997 as part of a Bristol University revue by Brigstocke, Tetsell and Danny Robins, was reprised in 1998 for Channel 4's ill fated comedy sketch show Barking and taken as a sample on Dee Kline's record.
An agent for the trio secured publishing rights to the track that entered the charts last week at number 11.
Dee Kline, 21, who first heard the line on a friend's voicemail, will make his debut on Top of the Pops tonight with MC Hyperactive providing lyrics.
Brigstocke, whose voice appeared on the track, was not invited to perform. But he said: "We've already been paid much more for this than the original work we did. Which is nice."
