Bono is big on tradition and spent Christmas Eve this year doing his traditional activity. The U2 frontman played on Dublin's Grafton Street to raise money for homeless charities. 

But that's not all. Bono also brought Hozier, the Script and some other Irish musicians to perform "Rudolph the Red-Nosed Reindeer," "When Love Comes to Town" and "Every Breaking Wave." 

Bono has been doing the Christmas Eve performance since 2009, with the exception of last year, when he was recovering from a bicycling accident in Central Park.
