John Lennon was a good rhythm guitar player. In my very humble opinion his genius was his rare ability to create beautiful melodies. Of course, music is a matter of personal taste. Hated his politics, respected his songwriting skills.
I find his legagy of songs mediocre. None of them move me. I much prefer the real authentic American bands that were almost his contemporaries (Grateful Dead, Quicksilver Messenger Service, Allman Brothers Band, etc.). With any musician, I listen to their music, not their politics.
A good live version of Morning Dew blows Lennon did out of the water, not even in the same league.
I think the beautiful melodies came much more from Paul McCartney.... nothing Lennon did after the Beatles amounted to much IMHO. With the Beatles, the best melodies usually came primarily from Paul. John Lennon was great in ensemble with the others and added a lot, of course, but I don’t get the sense that he was any musical genius the way his acolytes pretend. .......then again I don’t claim to be any musical expert, I just like what I like..... :^)
