Chevalier Theatre welcomes back comedian Kevin James for his first Medford appearance since 2019. James began his career as a stand-up on the Long Island comedy scene. After being discovered at the 1996 Montreal Comedy Festival, he signed a network development deal to create his own sitcom. “The King of Queens,” which premiered in 1998, ran for nine seasons on CBS with James starring and executive producing, and it garnered him an Emmy nomination for Outstanding Lead Actor in a Comedy Series. James also starred in and executive produced “The Crew,” a sitcom set in the world of NASCAR, and is currently developing a single camera comedy (both for Netflix). James brought his stand-up act to TV with “Sweat the Small Stuff,” a one-hour special for Comedy Central. Tickets are $63 to $97 through the Chevalier Theater website/Ticketmaster. To avoid online ordering fees, purchase tickets at the Chevalier Theatre Box Office, which is open on Fridays and Saturdays from noon to 6 p.m., as well as two hours before every Chevalier Theatre show. James will perform a second show at 7:30 p.m. on Saturday, May 18.
