As weird as Devo always seemed to be, before they signed with Warner Records they were a lot weirder.
Here is their original cover of "Secret Agent Man". You will note that they are all wearing creepy "serial killer" masks, and the guy in the baby mask (aka "Booji Boy") playing keyboards is Mark Mothersbaugh.
The arrangement is like the soundtrack to a nightmare.
I believe that's Jim Mothersbaugh on drums. By the time the band went (relatively) mainstream, he was replaced by Alan Myers. (And Bob Casale - aka Bob 2 - had yet to join).
The intro is from a 1984 public access video show.
