Green Day will never forget their time on stage at the 25th anniversary Woodstock show in 1994. At one point in the set, fans started throwing hunks of mud and sod at the stage. Green Day took this all very good-naturedly and started throwing stuff back. In fact, it was a pretty goofy scene–the audience and the band were covered in muck.
However, between the audience and the band was a line of security guards–and they didn’t appreciate being caught in the middle. Finally, one of them cracked. He leaped up on stage and tackled Green Day bassist Mike Dirnt. Mike fell against one of the stage monitors, busting up his arm and losing three teeth.
He needed emergency surgery to fix things up….and Green Day had to cancel one of that summer’s Lollapalooza gigs so Mike could heal.
