My current favorite song is Mumford & Sons "Little Lion Man". I recommend their full length debut, 2009's Sigh No More. If you like Bluegrass and British Alt Rock that is (kind of a weird combo but it really works). Anyway, check out this video. It's the band's American network television debut. Here they are on Letterman back in February (2010). Jimmy Fallon needs to have this band on their show (How did Letterman beat you to that punch?). Oh and we need to play this song on the Moose don't you think? Play the video and let us know (post a comment below).
