Elvis Costello and the White Stripes’ Jack White made surprise appearances during Bob Dylan’s Wednesday night (Sept. 19) concert at Nashville’s Ryman Auditorium. Although he and Dylan are officially scheduled to begin a tour together on Saturday (Sept. 22) in Duluth, Ga., Costello told the crowd he asked to open the show after learning Dylan was playing at the Ryman. Opening with “(The Angels Wanna Wear My) Red Shoes,” Costello walked onstage unannounced and performed a nine-song acoustic set that included “(What’s So Funny ’Bout) Peace, Love and Understanding” and “Veronica.” During Dylan’s set, White showed up with an electric guitar and sang “Meet Me in the Morning,” a song from Dylan’s Blood on the Tracks album. After White provided the lead vocals for most of the song, Dylan joined him at the microphone for the final verse. The White Stripes last week canceled all of their tour dates through the end of the year after announcing that drummer Meg White is unable to travel because of acute anxiety. Jack White produced Loretta Lynn’s critically-acclaimed album, Van Lear Rose, released in 2004. Dylan’s two-night stand at the Ryman concludes Thursday (Sept. 20).
