I spent a lot of years working shifts in commercial printing, Keith. Work a decade or so, get to day shift, shop goes TU, start over again, at a different shop, usually 11:00PM-7:00AM, spend another decade in the hole.
Repeat until dead. I earned every dollar that passed through my hands.
The only good thing on the airwaves, in the middle of the day, was Rush. I caught a lot of EIB programs, over the years.

Best,
Ted
