Were you really such a humbug fifty years ago? My parents were born during the Great Depression, and even they liked the Beatles in their day. Perhaps not as much as I did, but they weren't allergic to them.
Relax. I liked/like the Beatles’ music just about as most people did and still do. But the great legacy of the Decca label resides in their classical music recordings. Something that might not be recognized enough today - the Beatles did just fine on some other label, so their rejection by Decca did not deprive us of their talent. (And, for the record (heh!), I was not-quite-born-yet 50 years ago.)
Enjoy this evening with some of your favorite music, just as I will!
