Bogus blues men

Just put on the hat and you're done.
Now you're a bluesman, a bogus bluesman.
Just play three chords. That's the blues.

You're here with a high-end guitar?
Now you're a bluesman, a bogus bluesman.
Just play blue notes. That's the blues.

They kicked me out.
They said they can't listen to me.
They said your music isn't the blues.
What's going on?!
Tell me, Mr. Sonhouse.
You're my friend, Willie Brown.
Tell me what the blues is.
You're a bogus blues man.

If you sing with a joke that's not very funny while smelling of alcohol, that's the blues, right?
If it's a shuffle rhythm, it's the blues, right?
Well done, Mr. Bogus blues man.
