Yeah, the talent there was pretty amazing. McCartney made Lennon better, and Lennon made McCartney better. And then there was this guy named Harrison, who's backup singing couldn't be matched. Not to mention his own song contributions.
Too bad the guys couldn't keep it together for another 5 or 10 years. My fav's are probably Revolver, White Album, and Abby Road. But then there's A Hard Days Night, with some of the best sounding 60's country rock. Heck, it's all good.
