Dec 20th, 2017: Contract
 

It must have been for the 1965 US tour of the Beatles.
I'd never seen this before but seems to be a standard contract.

#5 isn't too shabby a location in a contract.
The way it's worded I guess they would play for white fans if they didn't suspect shenanigans in sales.
Or at least if it didn't hit the papers.

Mere amateurs.

This is the way to do it...
