Thanks everybody for the enlightenment. It's a pity the broadside gif couldn't be blown up any further to render it legible. The reference to Harry Garratt goes back to Rod Stradling who inserted the clause into the text I submitted referring to the Millen Family and other Kentish singers (see above) and also the double-CD of Sussex singers put out fairly recently. In both cases, I suspect the Vaughan Williams Memorial library source I quoted was his source. Nor was there an obvious candidate for Harry (or Henry) Garratt in any genealogocal source I'm aware of which might otherwise have helped.

I am intrigued by the genuine antiquity of this song. Doubtlessly, many country singers learnt it from Albert Richardson's record on Zonophone recorded in 1928. Cecil Sharp largely chose to ignore it, although I believe there were references to it in the Hammond and Gardiner collections at the VWML from the early 20th. century.

Now, who's Fred Alberts?
