Has there already been a discussion of this? I was listening to the Radio Shack/Realistic/Columbia Special Products sampler album "Back to Bernstein." One of the tracks is Leonard Bernstein conducting the 4th Tableau from Stravinsky's 'Petrouchka Suite' (aka "The Shrove-Tide Fair"). Checking my files, it doesn't appear that a quad version of the entire piece was ever released. It got me to thinking if there are other instances of this, whether classical, popular, or jazz. I seem to recall there was one Joe Walsh track from his 'So What' album that got put on a quad sampler even though the album wasn't released in quad. Help me out here, people.
