Spaw, I agree that Clapton's version of "Don't Think Twice" was the highlight of the 30th anniversary show. Two reasons for that: one, because Clapton's take on this song was so original, and so good; two, because most of the rest of the show (including Dylan's segment at the end) was so bad!

Seed and Mbo, "Across The Universe" was indeed a John Lennon composition (which he wrote by himself), and appeared on Let It Be. Lennon was very proud of the song, but not happy with the version on the album. To hear a very different (and, to my ears, vastly superior) version, check out the David Bowie/John Lennon collaboration on Bowie's "Young Americans" album. It has all the passion that the Beatles version lacks, and it may just change Seed's mind about the song.
