Amy Schumer, Judd Apatow and Glen Hansard were spotted having a right auld sing-song in Grogan's pub this afternoon.
The American comedian Schumer and top Hollywood producer Apatow are in Ireland at the moment to promote their new film Trainwreck, with a fantastic interview with Panti Bliss having taken place just last night.
The two American celebrities were then spotted today by surprised locals at Grogan's pub on South Williams Street where apparently they met up with our very own Glen Hansard for a wonderful rendition of 'The Auld Triangle.'
If that wasn't cool enough, they were actually serenading a newly-wed couple.
Check out the sing-song below.
