Other characters he played included Andy, Wolfman, Blue Beetle, Paul the Gorilla, Fred Baxter, Steve Awesome, and Lorelei Loverly.
Boyd also appeared in the 1974 TV movie Out to Lunch, a Children's Television Workshop production in which the Muppets and casts of Sesame Street and The Electric Company take over the ABC News when the newsroom staff takes a lunch break.
