Warning: I’m also a fan of Frankie Yankovic (same last name, but no relation to Weird Al). So you might get some “UHF” lines. Or you might get the "Just Because" polka lyrics.
OHmylanta! I love Polka! :D In a past life I was an event planner for a local but large annual festival and hired Polka Caller DJ’s. It was a hit from old to young and hip to nerds like me.
