WWRC-AM (980) has announced a "Swinging Into Spring" campaign for April, a daily schedule of artists associated with the swing era.

This slight departure from the station's regular offerings of standard bands and vocalists, said program director Kenneth Mellgren, "changes the flavor of the music but does not radically change the format." Each day will be devoted to an individual, group or category of artist (such as crooners), and three or four selections by Tony Bennett, Artie Shaw, Les Brown, the Mills Brothers, Harry James and Ella Fitzgerald, among others, will be played each hour, along with anecdotes about the artists.

WRC is kicking off the campaign with a dance at the Hyatt Regency Capitol Hill on March 31 at 7 p.m. and is also polling its listeners for their favorite swing song or artist. The results will be played on April 29. Coming and Going
