Enjoy ! Get Back, a very easy tab :

All along the song :
G---------------------------------7-7-7-7-7-7-7-7-------------------------------...
D-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7----------------7-7-7-7-7-7-7-7-7-7-7-7-7-7-7-7...

E-------------------------------------------------------------------------------...

It may sounds too easy, but Paul McCartney really plays this tab when he plays Get Back.
As it's a very easy one, you can try to sing along ;p)

Sorry for my english, I'm french,
