Mick Softley, English singer songwriter, died in 2017. I learned one of his songs, Gold Watch Blues, from the singing of Donovan Leitch. I don't think there is a tribute to Softley on Mudcat but it's difficult to find out as the search engine hasn't been functioning well for ages. I didn't find anything searching via the filter.
