When we were at college (In the pub) my friends and I had roaring good times singing 3/4 part harmonies to Young Tradition, Watersons tracks etc.
What about:
DIDO BENDIGO
POVERTY KNOCK
INNOCENT HARE
STORMALONG JOHN
WEARY WHALING GROUNDS
QUEENSLAND DROVER
RYBUCK SHEARER
CLICK GO THE SHEARS
NINE INCH NAILS

Oh the memories, the memories. We still sing some of these songs now,
they really get the blood rushing!
