The Beatles Let It Be



Listening to this song, I found Paul's pronunciation is so interesting. They are from the UK but it sounds more like...well, much closer to American English.(for US market?)

The first I thought someone...,an American or a Canadian singer covered this on this video but it wasn't like that. Paul McCartney is singing this, for sure!
yes,I knew this song (of course!) but I've never listened it carefully before.

So the Beatles was always like that...? Are they Americanized British Group?
Despite they are the symbol of the British pop ?


But listen to the below !

The Beatles Yesterday


It sounds like British English....
Same singer, Same group.But they are so different...

So...I think they change (arrange) their pronunciation by songs, for some reason.

I'm not sure if it's true or not.But as if there is an answer fot this ?
Maybe the answer will be "Let it be !"


What about us ?
Maybe...We use Japanese English:)


In addition to this topic : These two songs have one thing in common that both are considered about Paul's mother named Mary ( not about Virgin Mary) who passed away when he was young.
"Let it be" is the words from his mother in his dream when he really was in trouble with other band members.
And "yesterday" is his missing and longing for her.But it also sounds like an experience of his heartbreak. How do you feel ?
