John Mayer, Joss Stone drop in on Jeff Beck's gig

A day after Rod Stewart made a surprise appearance during his concert at Los Angeles' El Rey Theater, Rock and Roll Hall of Famer Jeff Beck was joined onstage Wednesday (4/24) by John Mayer and, for the second straight night, Joss Stone.

According to Mayer and Stone's publicist, Mayer took the stage with Beck during Wednesday's encore for a rendition of Jimi Hendrix's "Manic Depression." As she did the night before, Stone appeared for a rendition of Sly and the Family Stone's "I Want to Take You Higher."
