You were kidding that those were the Beatles, right?
No, they were, indeed, the Beatles--a group from Ardmore, Pa., who also recorded as the Lytations, the Five Scripts and the Kaptions.
The "other" Beatles may have embraced musical styles that included New Orleans-style rock and roll, country blues, string quartets, acid rock and even Hindu ragas, but I don't recall them ever doing East Coast vocal harmony like the Beatles of Ardmore, Pa.
