This could of came during my order of Ant-Bee "Lunar-Muzik" CD which was Billy James band w/ guest Michael Bruce, Neal Smith, and Glen Buxton. Also the CD included members of Mothers Of Invention and Captain Beefheart's Magic Band among other guests from the 60's & 70's. Billy James also assisted Michael Bruce on his book "No More Mr. Nice Guy".
So back in '97 I received this thick stapled pages of photocopies of order forms to articles
from past publications.
I separated this in 6 sections so here is 1 of 6.
On #16) Michael Bruce - Rarities
I don't believe this ever came out.
At least not to my knowledge.
