Entity,
I don't know where you heard that the entire album was written by anyone but DMB, but I don't think that's true. If you read the Rolling Stone article in this month's issue, it says they wrote the album. Also, if you download the band's reaction to Everyday, Carter says, "this is the best stuff WE'VE ever wrote." Glen Ballard produced the album...I can't find anywhere that says he helped in writing the songs. They've (the band) have always just written their own parts around Dave's lyrics. I don't know for sure though, that's just things I've seen and read.
ps - Holden Caufield, I'd have to say that #41 is the best song he's ever written...if you've seen it live, you might agree with me
