Musical selections formed the core of each broadcast, supplemented as "Crosby bantered back and forth with his co-stars in lively scripted exchanges laced with light humor.
He continued, "Bob Crosby ... is engaging in the light chatter ... and a good performer in his solos and duets with Margaret Whiting."
"[6] Other individuals who sang on Club Fifteen were Jo Stafford, Margaret Whiting, Patti Clayton, Evelyn Knight (singer)[7] and Gisele MacKenzie.
