Who originally sang "i swear" first...
John micheal-mongentry or all for one

I am thinking it is john Michael micheal-montgentry.
A friend is saying that it is all for one.

The BOTH came out with the song in 1994. However, I believe J.M.M.'s version was released first. (which was a very short time in between releases. I was working at a top 40 AND country radio stations at the time.) The song was written to be a crossover hit.
