A very rare clip has come to light of the Boomtown Rats on a 1980's comedy TV show called the 'Kenny Everett Video Show'. The Rats played 'Keep it Up' a track from the Fine Art of Surfacing album.
The song wasn't actually released as a single - it was just a fun song that suited the show. During the video, the Rats lark about in 1950's clothes and zombie make-up... for no particular reason... Also watch out for the gigantic guitar.
Watch from 4:54 onwards:
