The members of the group consisted of lead singer Mick Swagger (voiced by Christopher Cerf), a Green keyboardist (voiced by Brian Muehl), a Green bassist, a Fat Blue drummer and a Purple guitarist. The group is a parody of The Rolling Stones, although Mick Swagger and the bassist are the only Muppets who appear modeled after specific Stones, namely Mick Jagger and Ronnie Wood respectively.
