And another thing...

You ignored the quote from Peta Webb -

Walter had a large repertoire, 150 songs from Norfolk and beyond. Some were traditional ballads or songs of great battles, some about the experiences of young men and saucy young women ("The Maid of Australia"), some are from printed Broadsides ("The Dark-Eyed Sailor"), others are music hall tearjerkers, all sung with due respect and quiet relish.
