a woman's name, Ard Mhacha, and what food and drink (etc) he could get by composing and ode to her.

Despite my memory of having lost a cassette at that lark in the park, I do have a rainbow-covered cassette with peace songs in my possession. It's called "We Have a Dream" and was produced by Oneworld PeaceSongs of London. Unfortunately I didn't send Oneworld Peacesongs an SAE to receive a "lyrics sheet, with photos of the singers & more information".

Songs on the tape are:
Building Bridges/Stand Up (sung by 1world Peacesingers)
The Opposition (Margo Random, author and singer)
Four Minutes to Midnight
Carry Greenham Home (Peggy Seeger)
Like a Mountain (Naomi Littlebear Morena)
Tierra Sol (Cupido)
Speech to Apollo/Out of the Darkness (Frankie Armstrong)
Women Make Your Move (Rachel Hayhoe)
The Woman in Front of the Bus (Joanna Cazden)
Tomorrow (Peggy Seeger)
No More Genocide (Holly Near)
The Silo Song (Rebecca Johnson)
One World (Rachel Hayhoe)
