U2 have been showing a lot of love to their impersonators on this tour. Back in May, they brought a Bono impostor from the band Hollywood U2 on stage to sing “The Sweetest Thing.” As The Irish Examiner points out, they continued that trend last night in Toronto, inviting the cover band Acrobat to join them for a rousing rendition of “Desire.” U2TourFans.com explains that Acrobat includes Mark Baker aka @U2BROTHR, who was recently the subject of a film by director Michael Corbiere about his experience as a U2 fan. Watch fan-made footage of the performance below.
