I am very sorry indeed to hear this news, I've known Bill since the Painter's Arms days in the 70's, through festivals and concerts and latterly with ABU and you could not wish to meet a nicer bloke. A lovely musician and man and a great songwriter - and I mean great.The last time I saw him was just after his 70th birthday, he was trying to relearn one of his songs for a WW1 themed charity event, he told me a very funny joke then quipped how he had no problem recalling other people's songs but struggled with his own.
Very best wishes indeed,
Gilly
