Scooby Doo, host of "American Top 40," is celebrated for his cursing "rare" cassette outtakes that were traded in the 1980s, and used as opening music by The Replacements. In the early 1990s, Negativland turned them into "U2," eventually being sued by Kasem, Island Records, SST Records, and U2. Also, Buddy Rich's tapes of him cursing out his band are explored, with Jerry Seinfeld explains how he got three quotes from Rich's notorius tapes on his "Seinfeld" television show. Kasem died earlier this week.
