Okay, so I'm a couple of decades late, but I happen to be chord tabbing a few of Archie's songs.

For the benefit of Clinton Hammond (and anyone else), I think it's standard tuning and these are the chords, per the 5 lines per verse:

NOTE: The G in parentheses (G) seems to occur in the 1st verse only.
            G/B can be played as a Bass walk-down from C to Am on the A-string.

Am   (G)   D   G   Am
G   D   F   C   F
Dm7   G   Em
F   Dm7   C G/B Am
Bb   G
