The Lancaster high school marching band banned from playing Fall Out Boy and other pop songs because of potentially offensive lyrics (even though we're talking about instrumental versions here) got a big dose of support - from Fall Out Boy.

According to PennLive, the Garden Spot High School musicians joined the rockers on stage Sunday show in Scranton during a stop on Fall Out Boy's "Monumentour."

The news site said Fall Out Boy Tweeted this Monday: "GSHS were banned from playing fob at their games so we brought them to #MONUMENTOUR to play w us instead."
