Speaking of Jackson Browne, a few years ago I saw him in a benefit concert in a small venue with Bonnie Raitt and Keb Mo'. He was on stage doing some solo pickin' when he starts tuning up his electric guitar to do some slide work. His back was to the audience, fiddling with the guitar. He suddenly turns around with a sly grin on his face and says, "I know what you're thinking.... you're thinking what the hell am I doing trying to play slide guitar when Bonnie and Keb are backstage." Then he starts to play, and about thirty seconds into the song, he stops, goes to the mike, and says "Hey Bonnie, get out here and bail me out." So Bonnie came on and they played a duet, with Bonnie playing the slide part.
It was a great moment...seeing his humor, and acknowledging that his blues/slide guitar takes a back seat to Bonnie and Keb.
