The chords are C Dm G C

Mmm [C] mmm I wanna linger
Mmm [Dm] mmm a little longer
Mmm [G] mmm a little longer here with [C] you

Mmm [C] mmm it's such a perfect night
Mmm [Dm] mmm it doesn't seem quite right
Mmm [G] mmm that it should be my last with [C] you

Mmm [C] mmm and come September
Mmm [Dm] mmm I will remember
Mmm [G] mmm our camping days and friendship [C] too

Mmm [C] mmm and as the years go by
Mmm [Dm] mmm I'll think of you and sigh
Mmm [G] mmm this is good night and not good [C] bye
