Ray Bridges, who lives south of Indianapolis, plays his euphonium at Colts games. The horn has earned him the nickname "Tuba Guy" among other fans, as well as some Colts players. He'll be playing the song "Charge" at Sunday's game, which has the Colts playing against the Denver Broncos. Former Colts quarterback Peyton Manning, who now plays for the Broncos, will return to play at Lucas Oil Stadium for the first time since he left the Colts.
