Now THAT'S a coincidence -- I sang the chorus of this (to Curmudgeon and Kendall's dismay) at the Sinsull sing last night.

My version (which I've known since the mid-'60s and might be able, when I have the time, to find what book I got it out of) is slightly different --

There was a man in our town, I think his name was Lem
He prayed for prohibition but he voted R-U-M.
He helped to put the poison in his neighbor's C-U-P
And now he laughs at us because he's S-A-V-E-D.

chorus:
Oh, G-L-O-R-Y we are S-A-V-E-D.
H-A-P-P-Y to be F-R-double-E.
Oh, V-I-C-T-O-R-Y from the bonds of S-I-N,
Glory glory halleluyah, tra-la-la amen.

I, for one, would love to hear the tune you have and see how it compares with the tune as I remember it.
