Iron Maiden rocker Bruce Dickinson was shocked to discover octogenarian entertainer Sir Bruce Forsyth was in the audience at one of the band's gigs over the weekend (03-04Aug13). The heavy metal legends are currently on the U.K. leg of their Maiden England trek, and took to the stage at London's O2 Arena on Saturday night (03Aug12). Dickinson was stunned to find one famous face among the thousands of hard-rocking fans - 85-year-old TV star and gameshow king Forsyth. Telling the audience at Sunday's (04Aug13) show, he said, "We had Strictly Come Dancing in the house last night. "Bruce Forsyth was here, which is absolutely f**king unbelievable. I wish I'd have known, I would have said (Forsyth's catchphrase), 'Nice to see you, to see you nice.'" Forsyth has hosted U.K. TV talent show Strictly Come Dancing since 2004.
