In 1970, Townhill became the driving force of a plan not only to safeguard the future of the Choir School of St Mary’s Cathedral, Edinburgh but to transform it into a new and vibrant entity.[1] In 1972, the school was expanded into a specialist music school on the lines of the Yehudi Menuhin School, with Lord Menuhin becoming patron and referring to it as "my younger sister-school in Scotland".[2]
Townhill retired in 1991,[1] and his autobiographical memoir The Imp and the Thistle: The Story of a Life of Music Making was self-published in 2000.[4]
