Fascinato was a frequent performer and arranger on Chicago radio, often working with the Dinning Sisters trio on various series. He was the musical director for Starring Curt Massey (1943), and then spent a stint in the Navy. In 1948, after musicians' union head James Petrillo lifted a ban keeping musicians from performing live on television, Fascinato became musical director on Burr Tillstrom's Kukla, Fran and Ollie, playing piano accompaniment, arranging music for the occasional operettas (such as The Mikado), and writing songs for the puppet stars. He also backed Kukla star Fran Allison on The Fran Allison Show (1949).
