This article on the Strawbsweb site by Edmund Burke, Vice-Chancellor Bangor University, with contributions from various sources has a very comprehensive coverage of David Cousins' work

DAVID JOSEPH COUSINS 1940-2025

The last paragraph is interesting from a musical perspective:

"David Cousins’ last concert with the Strawbs was at the Cropredy Festival in August 2023. His final concert performance came as a guest artist at a Rick Wakeman concert in Folkestone in late 2024. However, David’s final public performance was during a visit to Bangor University on March 21st 2025. In the early days of his career, in November 1964, he had performed at Bangor University with the Strawberry Hill Boys. Over 60 years later, he returned to give two lectures in the Music Department to an appreciative audience of students and staff. It was a wonderful day, with David generously sharing his wisdom, humour, experience and expertise. His first lecture was a practical, informative, amusing and pragmatic guide to making a living in the music industry. The second lecture explored David’s process for writing songs while he demonstrated some of the unique tunings that he had used over his long songwriting career. David performed excerpts from some of his songs to illustrate his technique. It was the last time that he was to perform his brilliant and haunting songs in public. A new generation of music students had a marvellous opportunity to learn from the master songwriter.

"However, he will perform no more. The final words should come from David himself, taken from his masterpiece solo album, Two Weeks Last Summer:

“'Sad it is, but that's the way it ends.'”
