The Who's bassist, John Entwistle is dead of a heart attack. For quadness, the Who did Quadrophenia, unfortunately never released in quad. The soundtrack for Tommy is an unmarked QS recording, and may have been released in quad on tape. Even though not quad, the Who are to release a new STEREO remix of their first album, "The Who Sings 'My Generation'". Late summer for that, original album producer Shel Talmy is mixing that from his 3 track tapes www.sheltalmy.com.
