Danger Man was a British TV show starring Patrick McGoohan as secret agent John Drake. It ran over there from 1960 to 1962 and then they stopped making 'em for a while. They started up again in 1964 and made new episodes of a slightly-revamped version until '68 when Mr. McGoohan quit to do The Prisoner.
I know people who will argue until they're the color of a Smurf that The Prisoner was a sequel to Danger Man and that McGoohan was playing the same character. I also know people who will argue until they're the same hue that he was not John Drake in that show. Do not — repeat: DO NOT — send me your views on this because I don't care and because I think The Prisoner is a more interesting show if we aren't sure about that.
CBS aired Danger Man here in 1961. Later, when they brought the series back and aired the new version, it had a new title (Secret Agent) and a new theme song. The song was written by P.F. Sloan and Steve Barri, and Johnny Rivers recorded the short version heard on the show.
