 In the '60s and early '70s, CBS used a marching band-like composition called "Confidence" (taken from Leon Carr's score from the 1964 off-Broadway musical "The Secret Life of Walter Mitty") as their theme.By 1975, CBS had several themes (technically, CBS had different opening songs and graphics per crew) to open their broadcasts.They ranged from David Shire's "Manhattan Skyline" from the "Saturday Night Fever" soundtrack to "Fly, Robin, Fly" by the Silver Convention; the main title theme was usually "Horizontal Hold" by Jan Stoeckart.
