Dropkick Murphys -- Cancel Concert After Tour Bus Kills Pedestrian

The Celtic punk band Dropkick Murphys cancelled a concert in Tulsa scheduled for Sunday night after their tour bus struck and killed a pedestrian very early that morning.

The band was headed from San Antonio to the airport in Dallas when they say someone ran onto the highway and in front of their tour bus. The band says cops told them they suspect it was a suicide.

With their tour bus too damaged to continue on, and the bus driver severely shaken up, they tried to find other ways to Tulsa in order to make the gig ... but came up short.
