Luke Bryan Goes Gaga [Video]

Luke Bryan did a recent show, and tweaked his live playlist to include some Lady Gaga, and the Hairband Poison.  He performed Gaga's "Bad Romance", and really put some Umph into it.  Then the band went into Poision's "Nothin' But a Good Time".

Here's some fan video from the show, if you listen at the end, it sounds like they were starting into AC/DC's "Back In Black", but the video cuts off...
