Radio stars of the 1940s and early 1950s will be honored during an upcoming performance of “On the Air” at the Cumming Playhouse. Comedic greats such as Bob Hope, Red Skelton, Jack Benny and Jimmy Durante will be remembered through the 90-minute production, which focuses on the “Bob Hope Road Show.” The performance, which will be presented at 3 and 8 p.m. Saturday, Jan. 17, is staged as a 1940s NBC radio broadcast, complete with an on-stage staff announcer reading live commercials from the period, presenting recorded jingles of the era, and interacting with Bob Hope and his legendary radio and film star guests.
