It starred Frank Converse as Michael Alden, an amnesiac in search of his identity. Brian Bedford co-starred. The show's 13 episodes were filmed in 1965 and were originally intended to be shown during the 1965–66 television season, but CBS put the show on hiatus when they reversed an earlier decision to cancel the drama "Slattery's People". The network had plans to show "Coronet Blue" the following year, and CBS head of programming Michael Dann said that, "there still is enormous enthusiasm" for it, but it would take another full year before the network aired it as a summer replacement. It proved moderately popular and developed a cult following. According to Converse, CBS wanted to renew it but by then Converse had signed to do another series for ABC, " N.Y.P.D.", which premiered the day after the last airing of "Coronet Blue". Due to a number of pre-emptions, only 11 of the 13 episodes were shown during the initial run. The theme song was performed by rhythm and blues singer Lenny Welch.
