Stingray (1964)

S1E10 Titan Goes Pop

Believing the excitement at Marineville indicates the arrival of a distinguished guest, X20 seizes a man and presents him to Titan. To his astonishment, Titan discovers that X20 has captured Duke Dexter, a renowned pop star. Mistakenly, Titan thinks Dexter is a supporter of the sea dwellers due to the bizarre sounds he produces that drive the Terraneans wild. Impressed by this, Titan sets Dexter free to carry on with his 'beneficial' influence.
