Gwinnett County’s longest-running original theatrical holiday tradition combines the sentimentality of a television variety special with the high energy of a USO show. “Christmas Canteen” will begin its seasonal run Nov. 29 through Dec. 22 at Aurora Theatre in Lawrenceville. “This year, we were inspired by the Rat Pack Era in Vegas, a time where the entertainers owned a room and audiences felt special,” Aurora Theatre Producing Artistic Director Anthony Rodriguez said.
