Monterrey sez, "In what seems to be a college/high school show, three guys (Mario, Luigi and Princess Peach) play various famous Mario Bro's tunes with a marimba. Geeky fun!" This is hilarious — the band really gets into it, horsing around, doing all kinds of great physical comedy to the obvious delight of the audience.
Update: Lane sez, "I was at this performance at Francis Howell High School's talent show in 2005. The guys are Brian (Mario), Jeff (Luigi), Liz (Peach) and Adam on drums. The first three practiced this piece all through marching band season – really worked the crowds and other bands in the parking lots!"
