Knife Fight Ends a Tenacious D Concert in Las Vegas

People Can't Even Behave Themselves at a "Mock Rock" Show Anymore, Apparently

If you heard that a stabbing happened at a rock concert, you're immediately going to assume it was a heavy metal show, a rap group or some other highly-charged performance, right?

Not so in Las Vegas Saturday night, where a performance by Tenacious D -- the "mock rock"/comedy band made up of actor/musicians Jack Black and Kyle Gass -- was halted about halfway through when a man stabbed another man in the leg and left a large pool of blood near the stage, the Las Vegas Review-Journal reports.

The fight broke out at the House of Blues at the Mandalay Bay resort in Vegas, and police say two men were fighting before the stabbing incident occurred.

Police spokesman Jose Hernandez told the Review-Journal that one or two people were taken to the hospital, though neither suffered life-threatening injuries. One suspect was arrested at the House of Blues.

The concert, at the 1,500-capacity venue, was scheduled to last 90 minutes, but ended about an hour in. Concert attendees were made to stay at the venue until the area was secured.

Police didn't offer any specifics about what the suspect who was arrested might be charged with, or about what caused the tussle.

But we're pretty curious to know what possibly could have gotten people so riled up at a Tenacious D show.

Perhaps the gentlemen were still angry about the money they coughed up for Jack Black duds like Shallow Hal and Garfield: A Tail of Two Kitties?
