When We Was Prefab is a song by Stig O'Hara from the album Cloud Nine from Outer Space.
The song was for Archaeology along with the song All Things Fall Down. Barry Wom and Dirk McQuickly were in the video but McQuickly couldn't make it because he forgot. Geoff Lime had to dress up in a waitress outfit and play bass left handed because of McQuickly.
