File this one under “I did not know that” (said like Johnny Carson): If you look him up on IMDB (which I did recently, although I can’t exactly recall why) you will see that rocker Lowell George, he of Little Feat fame, made a cameo appearance on the sixties TV sitcom F Troop. In 1967 George portrayed a long-haired member of an anachronistic teen combo called The Bedbugs, the joke (one F Troop used more than once) being that you have a rock group right after the Civil War. Har!

Along with George, the other members of the Bedbugs were played by guitarists Warren S. Klein (who was in the Stooges circa 1973) and Martin F. Kibbee; and future Little Feat drummer Richie Hayward. At the time, the four of them were collectively known as The Factory. Frank Zappa would produce two songs for the group, which remained unreleased until 1993’s Lightning-Rod Man anthology.

After the Factory disbanded, Lowell would briefly join The Standells before becoming (again briefly) a member of Zappa’s Mothers of Invention, appearing on the Weasels Ripped My Flesh album on rhythm guitar. The teetotal Zappa either fired him, or George left voluntarily, over Lowell’s penchant for partying and pot.

The Factory would also appear in an episode of Gomer Pyle USMC but whatever song they were playing got removed from the eventual DVD release.
