That WALL has said a lot! One of my first shroomy trips had me listening to it back to back (cassette player going on auto-reverse :) 3 or 4 times. Kinda the first time I'd even considered my 'dad issues' - lots of basic overlaps with Roger Water's story as he tells it through this great ART piece.

This one may be next for Hyumis (according to @flamistan anyway ;)
