Deniz, Ron & Pip after Birdman went on to form The Visitors with Mark Sisto on vocals and Steve Harris on bass. Top poster is a pretty early one designed by Warwick Gilbert and purchased from Mark Kingsmill.
Bottom poster "The Death of the Visitors" could comfortably described as a fairly late one. The band Comrades of War was basically Birdman with Kannis on vocals, well that's what I was told.
PS: Nice "Bird-Mobile" MarkG!!
