Outtakes admittedly can be quite fascinating to listen to once, but like you say, how many people go back and ever listen to them again? I find that I rarely ever revisit the Beatles Anthology CDs for that reason - I've still got them all, but it's very seldom I ever get one of them out, and when I do, it's only to listen to one of the few fully-completed unavailable-elsewhere songs like "Real Love" or "Free As a Bird" or one of the previously-unreleased cuts like "That Means a Lot."
They could have put together a best-of from those albums that would have been a killer set (which is what I did, and it's one of my favorite disks to listen to).
Curious, what song on Fleetwood Mac did you think was weak? (I have a guess and a choice of my own but let's see if they match up.)
I actually made a CD of all the in-house TJB songs. Well, 31 of them -- that's another one I need to update for iPod use. There are around 4 dozen tracks total by Herb's stable of writers (and including Herb himself). I called my compilation Written In Brass.I have wanted to make a playlist of all the "TJB-family" tracks, composed by Herb and the band members (and including Julius Wechter and Sol Lake, Bud Coleman, etc.).
