Movie star Bruce Willis is returning to his singing roots this summer (06) as a guest on the ALLMAN BROTHERS BAND tour. The DIE HARD star, who scored a string of hits in the 1980s, will join the likes of Ben Harper, ROBERT RANDOLPH and Peter Frampton as an onstage guest of the rockers. The tour is set to be one of the biggest in America this summer after the Allman Brothers Band recently concluded a sold out, 14-night stint at New York's Beacon Theatre. The 26-date tour will kick off in Cincinnati, Ohio on 16 June (06).
