As part of the 45th anniversary, Summerfest is celebrating festival fans and giving them the chance to be part of its anniversary television commercials.

An open casting call will be held April 22 in The Garage at the Harley-Davidson Museum.

Summerfest is looking for their favorite Summerfest memory in 150 words or less. Audition participants are asked to bring a completed sign-up form and a photograph. Fans will enjoy live music and win prizes courtesy of Mambo, the Harley-Davidson Museum and Summerfest.

All attendees will receive one free 45th anniversary t-shirt and one free Summerfest ticket valid for July 4. Those unable to attend may submit their information online.
