[3] Media historian Jim Cox commented that in Club Fifteen, "Crosby followed a pattern that he had perfected a dozen years earlier, being the front man with the easygoing, laid-back technique, quick to defer to others in the cast."

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.

[3] Effective March 30, 1948, The Pied Pipers replaced The Modernaires, singing on Tuesdays and Thursdays as they alternated nights with the Andrews trio.
