The Mystic Knights of the Oingo Boingo
Their biggest claim to fame (beyond composing the title theme to John Hughes's seminal WEIRD SCIENCE) may be the launching of Danny Elfman as a major film composer, but they had a fascinating journey. Which included a feature musical called THE FORBIDDEN ZONE that is pretty out there.
Check out this clip of them on the original GONG SHOW in 1976.
(Note Buddy Hackett's wince-worthy comment.)
