The opening track from the self-titled major-label debut album by America's Got Talent season five winner Michael Grimm is a collaboration with Heart's Ann Wilson. Grimm told AOL Music: "I know Annie and I know Nancy [Wilson] from before, I would go out on the road and open for them. I know Nancy real well, but Anne I only met a few times - but I really wanted her to sing and she said yes and she happened to be in L.A. at the time. She came right out to the studio and she and I were looking at each other in the same booth, which is a very rare thing recording duets these days. They just don't do them like that anymore."
"Bittersweet Symphony" by The Verve samples an obscure orchestral arrangement of the 1965 Rolling Stones song "The Last Time." The Verve had to sign away most of the royalties before they could release the song.
