WATCH: U2 invites Bono impersonator on stage to sing with him

Bono invited Joe Hier, the lead singer of a U2 tribute band, on stage for The Sweetest Thing.

From Bono’s biking accident earlier in the year, to the death of their tour manager Dennis Sheehan yesterday, it’s been a tough few months for U2.

Though that didn’t stop them making one fan’s dreams come true during their LA Forum concert.
