Talking Heads, fresh-faced and downright cherubic.
When this song was recorded, Talking Heads were still a three-piece band—keyboardist Jerry Harrison had yet to join—and though the track lacks just about anything that would allow one to guess it was Talking Heads, David Byrne’s voice is unmistakable when he announces “This is an instrumental; we call it ‘Theme,’ but then we just keep it to ourselves.” The group opened for Television for that show.
Other than that, you can hear bits and pieces of the band that would become Talking Heads, but this is still pretty amateurish stuff. I, for one, find it comforting. It’s nice to be reminded that even Talking Heads weren’t always Talking Heads.
