Yes, I thought it could be either. However, I could find no suitable meaning for 'jade' in this context. I opted for 'jay' because the dictionary gives one meaning of 'jay' as a 'simple-minded or gullible person'. The transcription of 'Diamond Joe' from Lomax in the DT also gives 'jay' in a similar line: Click Here. What archaic meaning for 'jade' do you have in mind?
