Here's a little Shel Silverstein ditty I always liked as a slow blues:

The first part, as I recall it, in a talking blues style -

Now a friend of mine, way back in Chicago --
You know, he finally made his pile.
Well he got himself a mansion on Butler and Sheff
An' he was livin' in the latest style;
But I run into him, he was eatin' in a greasy spoon
While parked in front was his big limousine.
I said, "Buddy, you've got so much money
How come you're in here, eatin' beans?"
An' he said --

After you've been havin' steak for a long time,
Beans, beans taste fine.
An' after you've been drinkin' champagne and brandy
You gonna settle for wine.

He said "The world is funny, and people are strange,
And man is a creature of constant change, and
After you've been havin' steak for a long time
Beans, beans taste fine."

Now, you know I ran into another friend of mine
In a rowdy old Clark Street Bar.
I said, "Friend, is it true what I heard about you?
I heard you married a beautiful 18-year-old shapely movie star,
Yet here you sit, tryin' to make out with some barfly
Who's too old and ugly to be true."
He said, "Shelley, you're still a very young man
So sit down. I'll explain it all to you.

He said --
After you've been havin' steak for a long time
Beans, beans taste fine.
An' after you've been drinkin' champagne and Chivas Regal
You gonna settle for Thunderbird wine.
He said "The world is funny, and people are strange,
And man is a creature of constant change, and
After you've been havin' steak for a long time
Beans, beans taste fine."
