I’d never heard of Bill Hicks; truth be known, I had only a vague idea of Leary. So I did some learning. Found this on Wiki; damning.
Influence on Denis Leary
For many years, Hicks was friends with fellow comedian Denis Leary, but in 1993, he was angered by Leary’s album No Cure for Cancer, which featured lines and subject matter similar to his own routine.[ According to American Scream: The Bill Hicks Story by Cynthia True, upon hearing the album Hicks was furious. “All these years, aside from the occasional jibe, he had pretty much shrugged off Leary’s lifting. Comedians borrowed, stole stuff, and even bought bits from one another. Milton Berle and Robin Williams were famous for it. This was different. Leary had practically taken line for line huge chunks of Bill’s act and recorded it.” The friendship ended abruptly as a result.
At least three stand-up comedians have gone on the record stating they believe Leary stole Hicks’s material as well as his persona and attitude. In an interview, when Hicks was asked why he had quit smoking, he answered, “I just wanted to see if Denis would, too.” In another interview, Hicks said, “I have a scoop for you. I stole his [Leary’s] act. I camouflaged it with punchlines, and, to really throw people off, I did it before he did.” During a 2003 Comedy Central Roast of Denis Leary, comedian Lenny Clarke, a friend of Leary’s, said there was a carton of cigarettes backstage from Bill Hicks with the message, “Wish I had gotten these to you sooner.” This joke was cut from the final broadcast.
The controversy surrounding plagiarism is also mentioned in American Scream:
Leary was in Montreal hosting the “Nasty Show” at Club Soda, and Colleen [McGarr?] was coordinating the talent so she stood backstage and overheard Leary doing material incredibly similar to old Hicks riffs, including his perennial Jim Fixx joke: “Keith Richards outlived Jim Fixx, the runner and health nut. The plot thickens.” When Leary came offstage, Colleen, more stunned than angry, said, “Hey, you know that’s Bill Hicks’ material! Do you know that’s his material?” Leary stood there, stared at her without saying a word, and briskly left the dressing room.
