This is “Electric Worry” by the prog rock band Clutch. They may chafe at the term progressive rock but they sing about Riddley Walker, Minotaurs and have a delightfully absurd sense of humor. I recommend their album “From Beale Street to Oblivion” without reservation. My sister introduced me to them, and their album “Strange Cousins from the West” is also a great listen.
Doctor or lawyer I’ll never be
Life of a drifter, the only life for me
You can have your riches, all the gold you saved
Ain’t but room for one thing in everybody’s grave
