In news related to me last boost, TIL the #Primus album Sailing the Seas of Cheese was released just 11 days after Madison Wisconsin's Great Butter Flood/Fire. Also TIL that Great Butter Flood is a phrase that has escaped the lips of people who were entirely sober and not giggling even a little.
"Once the walls caved in, [the butter] came out like a river."

I am not currently aware of any evidence that Les or anyone else affiliated with the band was aware of the event.
