Hey people, if you have difficulty singing along to the first (real) version, my version 
just an alternate.  Try both and see which fits.

The chords are

G/Em/C/D

G Em      C           D           G
I'm just sitting here wasting my time
G         Em       C           D
until you come home from your escapades
G        Em     C           D             G
in the backyards with your friends of late
G       Em        C          D             G
I'd be worried if you didn't do this every spring
         Em         C            D               G
when the grass grows and there's birds in trees
        Em         C        D         G
and the sun shines, and you don't need me.
