Drunken Duet of the Day

The YouTube description is all you need to know:

I don't usually post covers of other people on here, but this needs to be seen! My best friend, Logan, the one that many of you know, lives in London now. Last night he had a show and after it he was headed home and got stopped by a drunk man who insisted that Logan teach him a song. This is honestly the most beautiful thing I've ever heard.
