Mickey Bradley played the Scaffold. Apparently there is a retrospective box set coming out. Here.
The Scaffold are a comedy, poetry and music trio from Liverpool, England, consisting of musical performer Mike McGear (real name Peter Michael McCartney, the brother of Paul McCartney), poet Roger McGough and comic entertainer John Gorman. They are perhaps most notable for their successful singles "Thank U Very Much" (1967) and the UK number 1 "Lily the Pink" (1968). Since initially disbanding in 1977, the group have occasionally re-formed for performances and projects.
I remember them from our childhood. There used to be a family radio show called something like Junior Choice and we requested this record. The BBC sent us a reel-to-reel of the dedication and song so we could listen again.
