Unknown song ... please help me!

   I'm having yet another problem. I was going through my .wav files and I
found a song labeled U2lif~2.wav; so I listened to it and it turns out that
it's Bono doing a duet with someone. My problem is...
 I have NO idea what the song is, who Bono is singing with or where it came
from! LOL I can't seem to upload it on to my web page either. So...... if
anyone is willing to help me out; please send me an email and I'd be more
than happy to send you the .wav file for your listening pleasure! I'm going
CRAZY over this, it's a good song and I want to know what it is!!!

Thanks for your help.

Amy.
