There used to be a saying that if a black performer — it was four theaters you had to play and be accepted before you would be accepted as a true entertainer. One of those theaters was the Howard Theatre in Washington, the Royal Theater in Baltimore and the master itself was the Apollo Theater in New York, in Harlem. … The fourth theater was the Regal Theater in Chicago. My manager said, “Do not go to New York trying to be Nat Cole or anybody else that’s trying to be slick, because there are people that are sweeping the floors that are much better than you’ll ever be. So the best thing for you to do is go there and be B.B. King. Sing ‘3 O’Clock Blues’; sing the songs that you sing the way you sing them. All these other people can do all of those other things, but they can’t be you as you can be you.” That I’ve tried to keep from then until now.
On the best advice his manager gave him — Quote from a Fresh Air (NPR) interview which originally aired on Oct. 22, 1996.
May you rest in peace and sing some heavenly blues.
