On July 17 only, “The Wedding Singer” becomes the Wagon Wheel Theatre’s 400th professional production since the theater’s inaugural year in 1955. For this special occasion, the Wagon Wheel Theatre will begin selling individual tickets beginning Wednesday for only $4. This special is only good for opening night. There will be giveaways prior to the 8 p.m. show and prizes to the max. Dress in your best 1980s costume to win gnarly prizes. If you think you’ve got what it takes, enter the breakdancing competition, or if you sing like Olivia Newton-John, enter the 1980s karaoke competition. The Wagon Wheel Theatre will give out four complete season subscriptions for the 2014 summer season among many other great prizes. Mark the date on your calendar because tickets will not last. “The Wedding Singer” is set in 1985 and Robbie Hart is a professional entertainer who lives with his Grandma Rosie in New Jersey. He makes his living singing and playing with his band at wedding receptions. After he publicly announces his own wedding day, his fiancé dumps him at the altar. Based on the original motion picture starring Adam Sandler and Drew Barrymore, “The Wedding Singer” opened on Broadway in 2006 and was nominated for a Tony Award for Best Musical.
