Fun reading the songs people have posted. I was thinking of "House of Gold." Someone mentioned it about halfway down the thread. Still, when you're trying to get by on a budget the words, "What good are gold and silver too, if your heart's not pure and true?" really resonate.
Right now my favorite is the verse from "Mole in the Ground" "Tempe wants a nine dollar shawl, (repeat), When I come round the hill with that forty dollar bill, it's baby where you been so long."
