Candidates for Re-mastering?

What would be your recommendations for great music, but not the greatest sound quality recordings (at least what is commercially available)...and thus would be at the top of your lists as candidates for re-mastering, or finding the orginal tapes to be reissued, SACD re-issues etc etc? The 'to die for" lists in stereophile and audiogon don't take this into account. Digital formats only.

Here are few of mine to get things started.
Beatles: Abbey Road, Sgt Pepper, Rubber Soul (if ABKO can do it for the Rolling Stones, can someone else do it for the Beatles, please!)
Weather Report: Heavy Weather: SACD available but done poorly in my opinion.
Led Zep IV
all of James Brown (especially Funk Power!) and Sly Stone recordings
