When I first arrived here on this forum, I obviously had not listened closely to the Beatles (particularly the albums prior to Rubber Soul, but even the ones after). I made the embarrassingly ignorant comment that the Beatles's strong suit was NOT harmonies, and that other bands have been better in that department.
Boy was I wrong! There's one silver lining of ignorance: when you correct it with something this pleasurable (discovering anew all the Beatles harmony singing I never noticed before), it's almost better than having it right the first time!
