Harpo Marx has been played on NTS in shows including FF w/ Toxe, featured first on 23 March 2020. Songs played include The Man I Love and Tea For Two.

Harpo Marx (1888-1964) was a member of the vaudville and motion picture comedy group the Marx Brothers. He was a self-taught harp player, and employed an alternate technique of his own invention. In 1957 and 1958 he recorded two albums, Harpo in Hi-Fi and Harpo at Work. These consisted mostly of older standards like "Laura" with Harpo either playing solo, or backed by strings or a soft-jazz combo. The two albums were released as a single CD on the Collector's Choice label in 2000.
