The most frequently asked question of The Swing Years and Beyond is “What is your theme?”
Played at the top of each Swing Years show, it’s "Royal Blue" from "The Pink Panther" soundtrack.
The film came out in 1963 and the album was released in 1964, featuring lounge and lush instrumentals by Henri Pancini … er, Mancini!
