Thanks for the tip, manXcat. It looks like a good site and I'll be checking it out.
As for the Beatles, I have my own sordid history with them, having turned down free tickets to their first-ever U.S. concert. About ten years later I met my much younger SIL who now is a Country DJ. Despite her being born in '66, she grew up as, and remains, a huge Beatles fan. The night I met her and my soon-be-wife's family she brought me an ashtray (for a bad habit long gone). As she handed me the ceramic, she said in low but wonderous child's voice, "Do you know that Paul McCartney was in a band before Wings?"
Have you seen the September '20 "Rolling Stone." Its cover story (and what a cool cover it is!): "The End of the Beatles: The Heartbreak, the Brotherhood, and Why the Music Matters 50 Years Later."
