Trainwreck proved that when comedian Amy Schumer and director Judd Apatow team up, good things happen. And apparently, the pair make a rather excellent musical duo as well. 

While in Dublin to promote Trainwreck, they stopped by Grogans pub, where a couple of newlyweds were having drinks with their wedding party. Also there was Irish singer-songwriter Glen Hansard (of Once fame and The Frames). So naturally, there was a lively singalong of Irish classic “The Auld Triangle.” Schumer seemed to have struggled with a few of the lyrics, but it’s still a rather impressive showing.
