Jesse Winchester appears to be a serial offender;

And a voice came down just like thunder
And light all around me shown
The voice said "Jesse get up And grab hold of my hand
Cause you can't stand up all alone"

from You can't stand up all alone

"Look, I have just discovered that I am
Fresh out of that herb that's so dear to me
You know what I mean man?"
He said, Look, Jesse, I'd like to help you, man"
Said, "I'm in business to supply you with the weed, you know
But the man just busted a whole huge shipment of mine
And now everyone in town's smokin' twigs and seeds"

from Twigs and Seeds

Creeque Alley was written by John and Michelle Phillips and mentions them both;

John and Mitchie were gettin' kind of itchy,
Just to leave the folk music behind.

Sebastian and Zal formed the Spoonful.
Michelle, John, and Denny, gettin' very tuneful.
