Here's a different version again from the 'Tararua Song Book', a homemade songster put together in New Zealand in 1943. I suspect it may have originally been an army version for route marching and may not have had a tune as such:
I'm saved I am, I'm saved I am, I'm S-A-V-E-D,
From the bonds of S-I-N I'm F-R- double E.
Once I was B-O-U-N-D to the D-E-V-I-L,
But now I know I cannot go to H-E- double L.
I'm saved on Monday, Tuesday, Wednesday,
Saved on Thursday too
I'm saved on Friday, Saturday, Sunday,
Saved the whole week through.
