This question goes back to the '60s but as a great deal of this mighty thread concerns the early days of the Liverpool 'folk scare' I thought I'd ask who was Hilary Watson?
Her name crops up in a Bothy guest list from 1965 (we paid her £3/10/0d!) and maybe she's the same Hilary who was on the very first flyer from 1964 when 'Hilary and Joan' were listed as 'Resident Guests.'
Odd term that I've always thought, but I wasn't actively involved at that time, being more concerned with getting the nuances of 'Louie, Louie' right with R&B outfit The System!
