Artificial Paradise was done, but it's sounds awfully fake with the echo/delay just poured on.
Jack Richardson told me in letters years ago that Bannatyne and Paramount were done, but were both vetoed due to being too long for the Q8 format.
I guess that means they couldn't have been LP-only releases because they pre-date CD-4? And a reel-only release seems silly. I'm sure RCA had their reasons but damn, I love Bannatyne and Live/Paramount is a wonderful snapshot of the Guess Who Live! in the early 70's.
