Purely in the interest of accuracy, when Richard cites The Young Tradition as adding a line (in fact it was an extra verse) to their recording of 'The Ploughshare' or 'Seasons'...
"There's a boy on a tractor a-going like hell,
And what farming is coming to sure no-one can tell"
...it was in fact Jim Copper (from whom they'd collected the song) who wrote it as his own comment on the modern methods of farming circa 1950.
This of course adds nothing to the debate except perhaps an English love of pedantry.
Some wit will no doubt think that should read peasantry.
