I’m appalled at how I spent my nights —
A type of Muzak for the well-to-do —
And if it hadn’t paid so very well
I’d rather’ve cleaned out cages in a zoo
The years I studied classics through long hours,
The awesome heights their genius understood;
Was now reduced to decorative noise,
A prostitute who wasn’t even
Good

The few times I have been to a piano bar type setting, I will say I was pleasantly pleased with the piano player.
For what those places typically pay, they can usually get decent musicians.
