Richard,

I don't know if you have access to Billy Bragg's recent book "Roots, Radicals and Rockers". He includes Bishop in there.

There is also "Skiffle" by Chas McDevitt which states "Bob Watson & Dickie co-wrote the song it was released in the USA but covered by Bobby Helms where it got into the country charts in 1957. Issued in the UK the following year it peaked at number 30 in the hit parade pushing Dickie's fine re-recording out of the ratings".

Hope this is of some help
