Arcade Fire fans can expect some special surprises during the band's three-night run at London's Wembley Arena. Wednesday night, the band was joined onstage by Chrissie Hynde, who jumped on the microphone for a cover of the Pretenders classic "Don't Get Me Wrong". Hynde and The National's Bryce Dessner returned for the encore to pitch in on the Arcade Fire's "Wake Up". Last week in Dublin, the band paid tribute to late Cranberries singer Dolores O'Riordan with a cover of "Linger".
