Part remix album, part theatrical souvenir, this sequence of hits serves as the soundtrack to Cirque du Soleil's Vegas-ready Michael Jackson: The Immortal World Tour. There’s as much "Earth Song" as "ABC," but ex- Jackson sideman Greg Phillinganes and producer Kevin Antunes come up with an interpretive mix-tape that balances string sweeps with imaginatively funky treatments of beloved cuts (see the wedding-reception-friendly "Immortal Megamix"). With Jackson's world-remaking grooves as a guide, even the gaudiest setting can be a party.

“Oh Sherrie”

Steve Perry's girlfriend Sherrie Swafford was actually in the studio when Perry began writing this song--his lone Top Ten hit as a solo act--with two co-writers. The trio began at midnight one night with just "Oh, Sherrie!" and "hold on, hold on." Three hours later, they had a complete song. Swafford, however, had to wait until the next day to hear it. "Sherrie actually got tired and went to bed," Perry said. She also appeared in the video, but their relationship did not hold on for long.
