SRS,Yup. "Who Mourns for Adonis" The small man who played the Puck like character also played Dr Miggilitto Lovelace in The Wild Wild West. Michael Dunn, who had a very fine singing voice. I believe he died very soon after the series ended.
Robert Heinlein's character, Noisy Reisling was a space poet and musician in the same stripe as Woody Guthrie. I believe that Heinlein said Guthrie was model for the character. One of Heinlein's poems The Green Hills of Earth, written by Reisling was spoken on a moon mission.
