I found this forum looking for the exact same song. I do have it on a VERY OLD and very scratched album, but would love to have it on CD. It is by Bobby Vee. I think you and I are the only people who ever heard it before.

another verse is
Holding hands and sitting close together
with the sun shining from above
Oh there's nothing like going to church on sunday, with the girl I love.

I don't think it was ever released as a single; just a "filler" on the album. I would like to have it for my sis and bro in law for their 40th anniv. as it was "their" song.
