My mother was the first African-American policewoman in Seattle - recruited, actually - and she did it for only 2 years, as she did not want to carry a gun. She worked mostly on domestic disturbances. The NAACP wanted her to do it. She did not actually have the temperament to be a cop - she was very sweet. She had a Masters in social work.
The thing about doing concerts is that it's doing a live show. It's on my schedule. It's songs I want to sing. It's saying what I want to say. It's working with the people I want to work with. I don't have to worry about pleasing other people - I can do what I want, and people come along and go for the ride.
