Hi:

I've been attempting to track down this same song for some time.

How well I remember the day I was christened
the water was cold and I let out a yell!
Old Jake McGuire was up in the choir (or or)
Playing the organ and it sounded like...
Dee da dum do da dum die da dum day
Dee da dum do da dum die da dum day
De da dum do da dum
De da dum do da dum
De da dum do da dum
Die da dum day

Have you had any luck finding the rest of the words?
