The result of the meeting of Michael McCartney (brother of Beatle Paul), who would work as Mike McGear to avoid accusations of coat-tailing, and Post Office engineer John Gorman, the Scaffold took a blend of absurd humor and catchy songs to chart-topping glory throughout the 1960s. Their lineup filled out with Roger McGough and Adrian Henri, the group was briefly known as the Liverpool One Fat Lady All Electric Show, to the horror of everyone around them. Henri soon departed. A change of name later, they were gaining a reputation as one of the most amusing outfits on the scene, with a residency at Peter Cook's Establishment Club (where the Bonzo Dog Doo-Dah Band also held court).
The Scaffold's biggest successes were their cheerfully silly singles, starting with "Thank U Very Much" and continuing with "Lily the Pink" (a sterilized adaptation of an old rugby song, featuring Jack Bruce on bass) and the somewhat incomprehensible "Gin Gan Goolie," all of which had a knack for sticking in the mind on endless repeat without causing undue annoyance. These three songs, in particular, are well remembered even as the 1990s draw to a close.
In 1973, the Scaffold officially ceased to exist, being blended into the immense stage antics of Grimms alongside a couple of former Bonzos and a great many other people. Three Grimms albums followed. The Scaffold made occasional reappearances for various purposes. During the 1970s, Michael McCartney would begin using his real name again, although his infrequent recordings would still use the McGear pseudonym. Post-music, he has pursued careers as a photographer and children's author.
