@f_dion @vinylrecords Ah yes. I love the Stravinsky and Prokofiev on the live album, but to my knowledge they didn't appear on a studio album...?
I do seem to recall some sleeve notes on Bermuda Triangle about there being a special surround sound-like version - I'll have to dig it out and check! :)
I guess that would have had to have been a special multi-track tape format or something at the time...
