A lesser-known byway of musical theatre is the Industrial Musical ('brand' shows for internal, in-company consumption by staff only) ~ what one might perhaps refer back to, in the spirit of the medium as a whole, as the 'cheesy face of capitalism', in the sense of somebody caught privately raiding the midnight fridge, their surprised mouth framed by telltale smears of So-&-So's cream cheese!
After which intro, you may be fractionally less astonished to consider the following titles of some such spectacles. These were almost all genuine, and no doubt much burnished and appreciated ~ apart from one impostor; which ONE is the fake?
The Bathrooms are Coming (American Standard, 1969)
Got to Investigate Silicones (General Electric, 1973)
You Belong in a Dodge (Dodge, 1969)
Our Golden Sun (Sun Products Corp., 1965)
