I stumbled across an old adding-machine shanty sung by computers in the days of hand cranked adding machines (c.f. Monty Python's Meaning of Life), called "What shall we do with the missing data?" (turn borrowed from "What shall we do with a drunken sailor?").
Shantyman: What shall we do with the missing data? (x3)
All: Early in the morning.
Chorus: Hoo-ray! Imputation! (x3)
Early in the morning.
The late John Thompson was a prolific and inimitable folk musician here in my hometown, along with his band "Cloudstreet." His version of "All for me grog" renamed "Across the Western Plains" is perfectly sublime.
Vale John, you are a hero of mine, I will do my part to continue your legacy in this small way.
