Intro: A, E, Bm, D

Verse 1:

A (x02220@1) It was you and me 
E (022100@1)and one hot summer
F#m (244222@1)Beading up with sweat 
Bm (x24432@1)all over each other 
D (xx0232@1)soaking wet.

A (x02220@1)We didn't have a lot of time 
E (022100@1)so we didn't waste much
F#m (244222@1)Finding all the right places 
Bm (x24432@1)you wanted me to touch.
D (xx0232@1)And all these memories 
D (xx0232@1)make it so hard to forget about me.

--------- Chorus:--------------
A (x02220@1)                        E (022100@1)I bet you wish you had me back
                         BmAnother (x24432@1)chance to get it just like that.
             DThe (xx0232@1)best you ever had.

A (x02220@1)                              E (022100@1)And do you close your eyes with her,
                      F#mAnd (244222@1)pretend I'm doing you again
     Bm (x24432@1)       DLike (xx0232@1)only I can
                          A (x02220@1)    EI (022100@1)bet you wish you had me back.
                          Bm (x24432@1)   DI (xx0232@1)bet you wish you had me back.

----------------------------------------------------

Verse 2: (same chords like Vers 1: A, E, F#m, Bm, D)
It was you and me 
it seemed to last forever
The way you taste 
and I still remember 
the sounds we made.

One day in June 
I stayed all night,
And made love to you like 
the Fourth of July
And all these memories 
make it so hard to forget about me
