These new songs – all debuted live in recent months but not yet released in studio versions – suggest Coldplay's forthcoming album may be more gritty, fun, strange and (yes) danceable than any so far: a Zooropa to the Unforgettable Fire of 2008's Viva la Vida. "Hurts Like Heaven" opened their Lollapalooza set with a word rush that occasionally recalled LCD Soundsystem's "All My Friends," plus some outstanding guitar asides. Broadcast on Jimmy Kimmel Live!, "Charlie Brown" (not the Coasters' 1959 hit, alas) triangulates Springsteen, U2 and Arcade Fire in a hood-rat oratorio that roars even if Chris Martin's delivery feels too genteel. "Us Against the World" (debuted at the Rock am Ring festival in Germany) is an anthemic ballad with sweet harmony vocals from drummer/secret weapon Will Champion. Most interesting may be "Princess of China," with a dubby drum track so huge, it apparently blew out all the bootleggers' mics in Nuremberg.

“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.
