The tune needs no introduction - it has attained the status of folk song, so that William Hills is long forgotten as its composer. Its other subtitle is The Drunkard's Song, which invites a certain briskness and raucousness of approach. I have attempted this - begging the well-mannered recorders' pardon - in the first part. The second, slow, part looks at the words, and treats them with a tender melancholy. Though no arrangement I can achieve could match the utterly haunting ballad-like performance attained in that magical moment by Charlene McKenna in BBC 1's Ripper Street.
