I first came across Frank in about 1969 when he was a member of 'Kings Shilling', who had just become resident group at Southport's Bothy Folk Club. He had a unique singing style and wide range of material to bring to the group. He was also very active in those days in the Liverpool folk music scene.
I had only seen him once or twice in the intervening years and was aware of his condition. I'm sure he will be remembered with affection by those who knew him.
Cheers
