The biography of Miles quoted by Joe above from the Allmusic site is largely correct except where it says:-

Wootton subsequently plunged into a full-time career of singing and writing, with a number of artists covering his songs

This is incorrect. Miles was a full-time teacher of foreign languages at schools and colleges in Brighton, although he did retire a few years early in health grounds. We had many conversations over the decades that I knew him about the joys of being a semi-pro musician with a daytime teaching job - we still had an income even in the lean months for gigs and a professional pension to look forward to when we retired.
