Paul McCartney has opened up about the Beatles business practices and says he's proud of the fact that they had anti-segregation policies worked into their contracts.

The policy was put in place in 1964 after the band discovered that a Florida venue planned to separate the audience by racial lines.

Paul McCartney revealed that he was reminded of the specific incident while working with Ron Howard on his new Beatles documentary:
"When we were making the film, all these little facts had come out and Ron was sifting through them with his team," McCartney tells Buzzfeed.com.

"We were due to play Jacksonville Florida in the States and we found out that it was going to be a segregated audience - blacks one side, whites the other - and it just seemed so mad, we couldn't understand that.

So we just said, 'We're not playing that!'"
