I had a hard time trying to get the chords to line up with the lyrics like i wanted, but 
basically its just
D----/A----/Em----/----  enjoy.

The little riff played after the Em is something like:

e--------------------------------------------|
B--------------------------------------------|
G--------------------------------------------|
D---2/4---2p0---0---2/4---4------------------|
A--------------------------------------------|
E--------------------------------------------|

D (xx0232@1)                     A (x02220@1)                 EmSeptember (022000@1)days are the nicest days of the years.
