Despite many releases/re-releases in the UK cinemas, Ford, I didn't hear this theme until a UK showing in the eighties on tv. But I knew it's credentials from being a fan of Patrick McGoohan via The Prisoner. I couldn't believe how good it was!
Obviously in the same tradition of Walt Disney's Zorro.
By the way, the Brian Tyler recording of the theme on the soundtrack to the new show is outstanding! Very true in tempo and orchestration to the original Morton Stevens recording for the show. I like to think it's perhaps exactly how it would have sounded to Morton while being recorded in the studio in the 60's (in mono for the show). A must-hear for fans of the theme!
