The 15-member Bowen Bottle Beer Band plays songs with beer bottles, of course. If their rendition of "Do You Hear What I Hear?" sounds too good to be real, their FAQ gives some details on how they make it happen (because...it's real). It doesn't mention whether they get drunk after a successful performance though. Watch the video after the jump.
