If there's one thing that Bono loves, it's Bono. Two Bonos are always better than one, in Bono's eyes.
We're kidding, we're kidding - sure Bono's grand. But that was exactly the scenario that the U2 frontman found himself faced with at their gig in Toronto the other night, although fans who nipped out to the toilet for a minute might have thought they were seeing double upon their return.
Canadian U2 tribute act Acrobat were at the gig, too, and were flabbergasted when Bono brought them on stage to play 'Desire'.
For a few minutes, the musicians - led by frontman/Bono lookalike Gabriel Pate - got to feel exactly what it was like to be the band that they impersonate. Two Bonos, two Edges, two Larrys and two Adams. Phew.
