The Big Sound was a radio format issued by Stars International. It was a series of 12-inch, 33 1/3 RPM records featuring celebrities delivering short messages to be used as “drop-ins” by radio stations subscribing to the service. Stewart appeared on several of these discs, including the one titled Big Sound Promos with Stars (B – 1R).
Side one features fully produced, with music and sound effects, short spots from each of the 15 stars listed. Side two has the same stars delivering the same messages, but with no music or sound effects.
