In another thread, there was a request for the chords. Here's what's in the Rise Up Singing songbook:

C - G7 - / - - C - / - C7 F - / D7 G -


CHORUS:
C CG C - / F FD G - / C C7 F D / C CG C -

The spaces separate measures, and the slashes separate lines. A dash means play the same as the previous measure. Two chords together, like AE, mean play A half the measure, and E the other half.
