Kai,this is a genuine LP, it is indeed Silly Wizard's first LP. It was released on XTRA records, a cut price Transadlantic Records label.
The band contains all the usual suspects Andy, Johnny, Mame, Gordon etc BUT Freeland Barbour plays the box not Phil Cunningham.
From memory the sound is very muddy, and like all XTRA records poorly pressed. The band were unhappy with the release and soon moved to Highway Records, Freeland left and was replaced by Johnny's brother Phil. I think it was eventually re-released on that label.
I will post a track list for you when I get home.
love, john.
