Favorite Beatles album is easy: Revolver. My favorite tune is much more difficult. Here's a few of my favorites.. in no particular order:
I'm generally a bigger fan of their earlier work. But, I'm a hopeless Beatles fan. Picking one favorite is really hard. I bet someone is gonna post another song I will wish I had picked. But, here's one that comes to mind -
“Here, There and Everywhere,” Revolver (1966)
My favorite is diffiantly yesterday
Back in the U.S.S.R.
I never cared for them.
