“The Saint” was a wonderful British television program based on the novels by Leslie Charteris. Roger Moore played the role of Simon Templar, the hero who would leave his “saint-ly” calling card, a stick figure with a halo. You should watch it some time!
Below are two different titles used during the show’s run – one in black & white and the other in color. The first one is just utilitarian, but the second one is very jazzy and hip (the second one was pulled off Youtube for copyright violation – boo!).
Black & White Intro (short & simple, with a jazzy theme)
Update (10/21/13): I found this intro and it is a one-off – much more cinematic!
