There are a number of grave digger songs and poems, most of them picturing the digger as an honest, hard-working man who is performing a necessary and noble service. Not one of them seems to be about the crafty, greedy seller of corpses to the Resurrection Men.
Through their interpreters, the song writers, all of the diggers seem to be stable, healthy, long-lived men who speak good, standard English and who would regard folk singer language as beneath them.
