I do not recall ever hearing that one, but it reminded me of a similar Willie call.
He too references the Madison tour stop on the one I am thinking of, so that call most likely also occurred around this time. He parodies "Lola" by the Kinks and it goes something like "moo-moo Mad-i-son" as he is making fun of the fat (his reference not mine) Wisconsin women
. I remember it pissed off some of the following callers too
. That one is also a hidden Willie gem but unfortunately I am too lazy to look for it right now.
