Chevalier Theatre favorite Bob Marley returns to Medford, celebrating 16 years as a stand-up comic. Marley is one of the hottest and most sought-after comedians in the country. He has been featured in his own special on Comedy Central, and is one of the few comics to do the complete late-night TV circuit: “The Late Show” with David Letterman, “The Tonight Show” with Jay Leno, “Late Night” with Conan O’Brien and “The Late Late Show” with Craig Ferguson and Craig Kilborn. Marley, a Maine native, uses biographical and observational material for his high-energy routines. Tickets are $46.50 through the Chevalier Theatre website/Ticketmaster. Tickets also may be purchased, free of online ordering fees, 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.
