Sure, but it's amazing that in that time the sound got that quality.
And remember that the don't use they own PA amplifiation. They sing with the system of the place!!! (Remeber Paul talking in Anthology about the Shea)
The Beatles - This Boy (Live)
I just love watching them sing this live!!
Interesting how (unlike the Rolling Stones) they didn't perform it the same way every time. On the record it's "... took my love awayyyyyyyy", and similarly on the other verses in the song. Here, live, it's "took my love away.", cutting it off short.
With their busy schedule (!!), how in the world did they have time to decide "Hey, tonight, let's sing it this way..."?
