Another sign of the times: the lady at the organ. She’d play the intros live for the local shows - and from the sound of the copy, she had her own show, which consisted of playing listener favorites on the organ. Or the novachord! The what? Wikipedia:

The Novachord is often considered to be the world's first commercial polyphonic synthesizer.[1][2][3] All-electronic, incorporating many circuit and control elements found in modern synths, and using subtractive synthesis to generate tones, it was designed by John M. Hanert, Laurens Hammond and C. N. Williams and manufactured by the Hammond company.[4] Only some 1069 examples were built over a period from 1939 to 1942. It was one of very few electronic products released by Hammond that was not intended to emulate the sound of an organ.

So she was the Vangelis of her day, then.
