U2 frontman Bono appeared at the annual Christmas Eve Busk with The Edge. Bono wore an olive green jacket and blue circular shades that harkened back to John Lennon. The Edge appeared in a grey beanie, a grey scar, and a black suit jacket.

The Christmas Eve Busk is part of an annual event in Dublin, Ireland, to help the city’s homeless population. The U2 members were part of an all-star Irish lineup that included organizer Glen Hansard of the Swell Season, Damien Rice and Imelda May that performed on a makeshift stage on Grafton Street.

The pair were introduced as “two lads from north Dublin.”

The performed “Love Is Bigger Than Anything In Its Way,” as well as a pair of Christmas carols, “O Holy Night” and “O Night Divine.” Then, they teamed up with some more Irish acts for a rendition of Mariah Carey‘s “Christmas (Baby Please Come Home).”

The Grafton Street performance is the third time Bono has taken part in the busking. In 2015, he sang “Every Breaking Wave” and “When love comes to town.” His 2009 appearance was limited to an ensemble support contribution.

Proceeds from the busking will go to the Simon Community, a homeless charity in the city.

The performance came on the heels of Bono suffering a “complete loss of voice” during a concert in Berlin earlier this year. The 58-year-old would ask for a 15-minute break and that the air condition be turned on and the smoke machines turned off.

He said: ‘I can promise you I have not been smoking. But this is like a giant cigar. I’ve lost my voice and I don’t know what to do… it was singing like a bird about 10 minutes ago.

However, Bono never returned to the stage and instead went to seek “medical advice.”

The audience noted that his voice sounded back to normal during his performance on Monday.
