The intro, goes with an E5  played in eights, and then we have:

This is the riff for the lead guitar.. If you play it by yourself you'd better
stick to E5  or perhaps an E7 -chord for the two first measures..

This is also repeated twice.. And VOILA.. Get Back.. I'm not sure about the
end though, but then again I don't think the Beatles were two sure about that
either...

Jojo was a man who thought he was a loner,

But he knew it couldn't last.

Jojo left his home in Tuscon, Arizona
A                     A 
For some California grass
D                   A  G D 

Get back,  get back
A          A 
Back to where you once belonged
D                        A      G D 
Get back,  get back
A          A 
Back to where you once belonged - Get back Jo!

Electric Piano solo - same chords as verse

Chorus

Sweet Loretta Martin thought she was a woman,
But she was another man.
All the girls around her said she's got it comin',
But she gets it while she can.
