Tia Carrere attended the Chiller Theatre Expo at the Hilton Parsippany on October 31, 2009 in Parsippany, New Jersey.
She performed “Ballroom Blitz”, the song she sang in Wayne’s World.

There are a few videos made by people who were actually there, but the one with better quality is THIS.

Two other videos of the same performance.
