Chevalier Theatre welcomes back Brian Regan, called “The funniest stand-up alive” by Vanity Fair and “Your favorite comedian’s favorite comedian” by Entertainment Weekly. Regan uses observational, sarcastic, and self-deprecating humor and has built a 30-plus year career on the strength of his material alone. Tickets are $39 to $69 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.
