As noted, lots of blues songs start off with "I woke up ... ."

There should be nearly as many possible variations on "I did not wake up ... ."

All you have to do is write the one that sells the best.

("Sales" to be in the currency of your choice. I'm a bit short on all kinds except congrats and applause at the moment.)

My baby ain't gone and left me
My old hound dog ain't died
So how 'm I s'posed to sing the blues
When even my lawyer aint' lied

I'm just a l-o-o-o-s-er
When it comes to singing blues
'Cause no one wants to listen
When you've only got good news.

John
