This week, the Okoboji Summer Theatre will wrap up its 65th Anniversary season with "The Wedding Singer." The musical performance is based on the hit Adam Sandler and Drew Barrymore movie, which takes audiences back to a time when hair was big, greed was good, collars were up and a wedding singer might just be the coolest guy in the room. Set in 1985, rock star wannabe Robbie Hart is New Jersey's favorite wedding singer.
