A couple of sources have checked in on the McCartney rarities CD set rumor and haven't heard or expressed doubts about it. (If you didn't see the track list, it's here.) We always have doubts about these internet rumors until indications are firmer. At this point, they're not. That doesn't mean it won't happen, but don't bet the house on it right now.
(5/16/2009) Depending on how much you want to believe, there may or may not be an unreleased McCartney/Wings three or four CD set in the works and a working track list to go with it. An EMI spokesman wouldn't comment when we asked if such a project was in the works, but Beatlefan's Bill King told us the magazine had mentioned in its most recent issue that it was reportedly under consideration. Now, a track list for such a project that was said to have been leaked from Abbey Road and apparently printed in Beatlefan/EXTRA! has begun circulating. You can see the rumored track list here, though again we stress it's just a rumor. Also, it's a project that has been discussed on and off for a long, long, long time. Is it happening this time? Stay tuned.
