I saw Miles Wootton in 1979 or 1980 performing at the Hoddesdon Folk Club, near London. I do not recall seeing him billed since, but I am in Northern England, and some performers still tend to be found in certain regions.
Sorry I cannot be of more help.
As Arbuthnot states, Fred Wedlock recorded a goodly number of Miles' songs. I don't have any record sleeves available to check which ones are credited though.
Quack!
