Abbot and Costello had a LOT of different shows. I've been listening to two different ones, both sponsored by Camel cigarettes. Both are "Camel Cigarette show starring Abbot and Costello." The opener for one is "C for comedy, A for Abbot, M for music, E for entertainment, and L for Lou Costello," and the opener for the other is "C, A M, EL, S -- Camels, first in the Service, first worldwide! Camels are smoked by more men in all the services than any other cigarette, as told by actual PX sales records!"
