Stormy Monday Blues lyrics

I said they call it Stormy Monday
But I said Tuesday's just as bad.
I said they call it Stormy Monday
Tuesday is just as bad.
Wednesday's full of sorrow,
I said that Thursday's oh-so, it's oh-so-sad. It's oh-so-sad.
I said lord, lord, why don't you have mercy,
You gotta have mercy on me.
So I'm trying to find my woman,
Won't you bring her home to me?
I said they call it stormy Monday.
