Mariah sings "I'll Be There"

This is probably my favorite Jackson song, and every time I hear the Mariah Carey version, I'm disappointed. I like Michael's version so much better. But this was really touching in my opinion. It was obviously performed live, which we don't seem to get very often. It wasn't perfect, but that's what made it meaningful.

I don't mean to sound like a huge fool, but I really don't know who the male performer is... Trey Lorenz? Wikipedia says he performed this song with Mariah as a backup singer in 1992.
