I bought a whole stack of Les Barker books a few years back. I wish somebody would tell me where I put them....Mainly Norfolk has a nice page on Les Barker: https://www.mainlynorfolk.info/mrs.ackroyd/songs/
And this page has lots of information and links: https://pennyspoetry.fandom.com/wiki/Les_Barker
Or you can come to the Mudcat Worldwide Singaround most every Monday, and you can hear Pelagie do her wonderful interpretations of Les Barker's works.
