Mike Cross' tune was not Little Boxes, I must've been thinking of Malvina at the time. Mike's tune was Little Ditches, about a family who all worked in the undertaking business.
"We made our riches
Putting folks in little ditches
Six feet under the ground."

"Papa looked just like an old church deacon
But underneath he really was a clown.
He said,"Folks are just dying for our service
And you know we'd be the last to let 'em down."
