For 15 years, Alan Lambert has been bringing Tulsans the tunes of Benny Goodman, Glenn Miller and more with his popular radio show Big Band Saturday Night on KWGS. Lambert’s career also included work in Tulsa television and stints as news director of KVOO and general manager of college radio station KRSC. To commemorate Lambert’s 50 years in Tulsa-area broadcasting, Public Radio Tulsa presents “Big Band Saturday Night! Live from the Crystal Ballroom." Guests are encouraged to dress in 1930s and ’40s garb to help set the tone for the evening; otherwise, cocktail attire is suggested. There will be opportunities to record personal memories of other nights at the Crystal Ballroom to be archived in the Mayo Hotel’s museum. Tickets are $40 each and include hors d’oeuvres. A cash bar will be available.
