Look out kid
It's somethin' you did
God knows when

You better duck down the alley way
Lookin' for a new frien'
The man in the coon-skin cap
In the big pen
Wants eleven dollar bills
You only got ten.

I suspect the adhesive will eventually embrittle and crack, resulting in the same squeaking problems as before.
In sheet mills the custom of two rollers working level-handed (dividing the pay evenly), instead of one roller working with a helper, has been increasing in recent years.
