Whenever he can, Mr. SLS goes out to the Metro during rush hours to play. Sometimes he's alone, other times he's joined by some friends. He does it as a way to mix up practicing (much more interesting than playing scales in our living room with the cats staring at him from the piano bench and windowsill).
The money he makes doing it ebbs and flows depending on the Metro, the weather, the day, the crowd -- anything. Though I don't go with him, I get a cut off the top of all cash monies earned. LOL!
Anyway, this cartoon made me think about all of that so, you got a blog post!
