After "Cricket Star" in the Discography should appear "Lord Of The Hornets" b/w "The Greenfly And The Rose" (single, Flicknife, 1980). Both tracks credit Calvert with words and vocals.

At least one Calvert poem did appear in Frendz, but within a prose piece by him. 12 lines, rhymed, ending "But when the concert is ended / with the last round of applause / Silence begins to doze again / you can hear its ragged shores", it appears in "The Last Of The Listening Ears", Frendz #28, May 1972. (Reprinted, with 5 other Calvert prose vignettes from the magazine, by Zephyr Hawkfrendz, 2001 - £1 from Trevor Hughes, POB 6, Liscard, Wallasey L45 4SJ, England)
Re: Steve Sneyd's Gnawing Medusa's Flesh chapter - Regarding the appearance in Science Fiction Monthly suggested by Brian Tawn, from a secondary source, Andrew Darlington has since gained access to a full run of that publication, and no poem under Robert Calvert's name appears there.
