Harper referenced this programme earlier in his career on his 1969 album Folkjokeopus, with a track entitled "McGoohans Blues".
The album is notable for the lengthy track "McGoohan's Blues", which Harper states was "inspired by actor Patrick McGoohan's depiction of the establishment rebel in his TV series, The Prisoner".

The album title was borrowed to provide the name of a Minneapolis record store, Oar Folkjokeopus.
