Hello
Having thought over it, and some more songs occurred to me. What do you think about:
Tears in Heaven by Eric Clapton (too beautiful to be true... awesome song... makes me cry..)
I Don't Wanna Miss a Thing by Aerosmith
November Rain by Guns N' Roses (woooooohhhhhhh such a great song, goooooosebumbs all over..:-)
Stairway to Heaven by Led Zeppelin (a masterpiece of a song, perhaps 8minutes are too long, but dj could sing a short version?)
Anyway, I think David Jordan could sing the using instruction of a spanish washingmachine and it would sound great.... 
He definitely has THE voice 
OMG
I'm going to write nonsens, so i better stop.
Love you all
