As most of us know by now, XTC's return to the U.S. limelight, "Dear God," was originally left off of the 1987 release, "Skylarking." It had been relegated to a B-side. First pressings of Bob Dylan's "Shot Of Love," a record I happen to think gets unfairly bundled together with his "mediocre" Christian records, was made even better when second pressings added the killer track, "The Groom's Still Waiting At The Altar." I mention these records after listening to "Susan," a track from Aimee Mann's stellar 2000 release, "Bachelor No. 2," and a track that was not on the original 7 track extended play CD. There are many wonderful songs on Mann's best record, "Bachelor No. 2," but I happen to love "Susan."
Excluding B-sides and favorite unreleased tracks, of which there are many, can you think of songs that you absolutely love that were specifically left off of, or subsequently removed from, a record?
