In Ireland’s capital city for Trainwreck’s European press tour, Amy Schumer, director Judd Apatow, and unrelated third party Glen Hansard (of Irish band the Frames) stopped into a local pub and pulled something right out of the Bill Murray playbook: seeing a wedding party under way, Hansard was asked to play a few timeless Irish tunes for the newlywed young couple. Schumer and Apatow, of course, couldn’t resist contributing some backup vocals, and what ensues is a pint-fueled sing-along for the ages. How does she know the words to this Irish folk song? Schumer is obviously a fan of all “Insideâ€-titled projects, including Inside Llewyn Davis.
