“I don’t have too much good to say about George Harrison, but he did write some good songs and made a lot of good songs better.”
Pretty good guitarist actually.
He was pretty good, but his songwriting often tended toward the banal (not always, though. He wrote some stellar songs) and his singing was not so hot and he was somewhat dour. He was good enough, but compared to Lennon and McCartney, he was second rate.
Which may be unfair. Most are second rate compared to Lennon and McCartney.
Just to expose my prejudices, I’m a huge, gigantic fan of mid 60s folk rock and the Byrds are maybe my favorite group ever. So the stuff from Help through Revolver is pretty much my favorite music of all time.
