Martin Luther.
Some say that he wrote "A Mighty Fortress is our God" around a tavern drinking song melody. Others dispute this; it bothers them. Maybe it was just a popular melody hitched a ride with the people who went to those places.
But since this is so controversial, how 'bout this guy?
Yup. Bach.
He ripped off Luther!
Served Luther right.
Evidently, having only 12 notes isn't easy enough for these scamps. They have to copy each others' work!
How this den of thieves howls and cries foul when they get served their own broth!
Musicians.
They deserve no consideration, whatsoever, in any civilized society.
And their agents, publishers, enablers?
Even less.
(By the way, I ripped off the artist who painted these pics. Sorry. Fortunately,their dead.)
