Hmmm, as much fun as The Beatles seemed to be having performing, they never talked like they thought their music was so great. One of my favorite lines in A Hard Day's Night is right after "I'm Happy Just to Dance with You" when Paul says, "Well, we're trying." And they referred to lots of their early work as "throwaways", "bits and pieces" stuck together, or even "rubbish". John was positively brutal in later interviews saying that in the beginning they were trying to emulate other artists, and that often "it didn't work." Perhaps Jerry saw it from the same perspective?
I wonder what Garcia thought of their later work?

I remember John said he would have been embarrassed to sing "I'm Happy Just To Dance With You." It was given to George. I think George did fine on songs like this and other early songs, too, whether they were originals or covers such as "Roll Over Beethoven." In this respect, I don't feel he got the credit he deserved. My only criticism of him would be a few of his solo albums such as "Somewhere in England" which was somewhat lacking, IMO.
As for throwaways, a few of the songs probably shouldn't have been recorded. It seems Paul said something to this effect about "All Together Now." I agree.
John Lennon was always critical even of some of his best music. There is no way anyone who wasn't a Beatle can even begin to look at things like this objectively. Personally, I think he was way too hard on himself, though. I can't even speculate what Jerry Garcia might have thought. I was never really a Grateful Dead fan and can't say much about them one way or another. But I thought those comments Garcia made in that article were very relevant and interesting. It certainly caused me to look at him in a favorable light.
