Richie,
When did Mike record 'Young Willie'? A close mate of ours, Jim Eldon, was singing this version in the 60s in Hull. I'm pretty certain it's the McCluskey version. I always loved this version. They probably got it from the 1956 Folk Music Journal of the EFDSS as transcribed by Peter Kennedy and Michael Bell. I'll check out Jim's recording and see who got it from who.
