Right Said Fred was a British pop band formed in 1989 by brothers Richard and Fred Fairbrass. The band's 1991 song "I'm Too Sexy", a tongue-in-cheek dance song sung from the point of view of a vain male fashion model, was a breakout hit, reaching #2 in the UK charts and #1 in the United States.

The Muppets appeared with Right Said Fred at the 1993 Royal Variety Performance. The band was introduced by Kermit, Miss Piggy and Gonzo, and performed a medley with the Muppet Monsters.
