Bono invited the Toronto U2 tribute band Acrobat onstage Monday night to perform “Desire” during a show at the Air Canada Center. Acrobat frontman Gabriel Pate gave Rolling Stone all the details on meeting Bono, getting onstage and dueling harmonicas. Pate said, “The first time that Bono pulled me onstage was at a Detroit show about 10 years ago. My dream for the longest time was to sing with him, but he didn’t want to do it that night and he told a bunch of jokes about me and then I got down.” Pate then added, “I’ve bumped into him at shows and he always gives me a little bit of acknowledgement. I’ve also gotten to know members of U2’s crew. When they were done with the Chicago shows, I e-mailed them and said, “Hey, we’re going to be in Toronto with the band. Who knows what might happen?”
