Buying the albums sampled on “You Can All Join In”.
As far as I know, the LP was only ever available on the lovely pink label:
The back cover looks like this:
It gives a track listing and these sparse credits:
“Art direction : Mike Sida Recording Engineer: Andrew Johns”
I know of no other instance where he was not called “Andy Johns”.
The CDs have cover notes in their inserts, with some degree of overlap. Next time we shall start having a look in those for the sampled album.
