It may have been a musical triumph, but U2, and The Edge in particular, won't forget the opening night of their Innocence + Experience tour for all the wrong reasons.
The guitarist fell off, or rather, absent-mindedly walked off, the band's elevated walk-way mid-way through a performance of I Still Haven't Found What I'm Looking For at their concert in Rogers Arena in Vancouver.
Security guards helped The Edge back on stage after his "senior moment" and the band completed the song which was their finale on a triumphant night.
The Edge took to U2's official Instagram account to let fans know he had walked away relatively unscathed from the embarrassing incident.
"Didn't see the edge, I'm ok!" he captioned, displaying a picture of his grazed arm.
Of course, the incident was captured on video and quickly posted on YouTube, garnering nearly 600,000 views around the world.
It's only six months since lead singer Bono suffered serious injuries when he crashed his road bike in Central Park in New York.
Unlike The Edge's lucky escape, Bono is still recovering from the accident and unable to play guitar.
Those injuries included a facial fracture around the orbit of his eye, three separate fractures of his left shoulder blade and a fracture of his left humerus bone in his upper arm.
The arm injury was deemed particularly serious with the bone breaking in six different places and a shattered bone tearing through his skin.
Tomorrow night, the band will perform the first of two dates in San Jose before moving on to Phoenix, Arizona and LA.
All those shows have been sold out and Rolling Stone raved: "They played this show like a young band with something to prove, and this tour is only going to get better as the year goes on."
