If you take song lyrics literally, then the wage was 25 cents an hour.
That was the minimum hourly wage in 1938 when federal law first
established a minimum wage amount.
You could add maybe five years to 1938 because a vagabond hobo would
not be paid for pushing the broom, but might be given a room in
exchange for two hours of labor in a flophouse that rented rooms for
50 cents a night.
Or, you could see the "four-bit room" to be a description of a room
that *should* have cost 50 cents a night for what you got, but
actually cost $2.50 a night. (The minimum wage in 1964 was $1.25 an
hour)
But, is it right to take song lyrics literally?
If you took your Chevy to the levee you should have expected the levee
to be dry. A levee is a raised embankment that prevents a river from
overflowing. There would have to be a major flood for the levee not
to be dry, and you'd know that before driving out to meet the good ole
boys drinking whiskey 'n rye.
Why would you want to go to a place that swings like a pendulum do?
Pendulums swing in a absolutely predictable manner and never move
outside of a confined arc of space. A dull action at best, even when
wound up.
If she just received a brand new pair of roller skates, you would
think they would have come with a key. Besides, she rode past his
house on her new roller skates the night before, so she must have had
a key to tighten the clamps.
Sometimes lyrics are written just to rhyme or fit.
