Agree 100%, @rpeluso. I know there are Robertson apologists, but I see right through his self-serving rationalizations for what he did. He is a fine guitarist and songwriter (or rather was), a terrible singer (he "fakes" singing all throughout The Last Waltz. I find his solo albums unlistenable, and quite pretentious.), and not much of a friend.
In his autobiography (Testimonial, which I refrained from reading until very recently, out of respect for Levon. It’s actually fantastic, the best retelling of their story I’ve read.), Robertson talks about the songwriting credits issue, and his explanation sounds very bogus. I stood next to him at a movie theater on Sunset Blvd. in the early-2000’s, and was sorely tempted to say something nasty to him. Let it go, Eric ;-) .
It was Levon who had a great post-Band career, not Robbie. Including a Grammy for one of his albums. A not bad actor, too (The Coal Miner’s Daughter, The Right Stuff, a couple others). You’ll notice Muddy Waters walks right past Robertson as he exits The Last Waltz stage, over to Levon’s drum riser to shake his hand. During rehearsals it became apparent the show was running long, and Robertson asked Levon to tell Muddy they were going to have to cut him from the show (instead of Neil Diamond?! Robertson was at that time producing Diamond’s in-progress recordings sessions ;-). Levon replied "If Muddy don’t play, I don’t play." When Muddy’s segment became a highlight of The Last Waltz film (in spite of Robertson’s showboating on guitar, and his uncalled-for vocal proclamations), Robertson acted as is having Muddy on the roster was his doing. He’s shameless.
By the way, there’s a video on You tube chronicling Garth Hudson’s revisiting the Big Pink house, and speaking with it’s current owner (a musician). It’s fantastic, including a snippet of Garth displaying his incredible prowess on piano.
