My favorite is when he was on tour. He checked into a hotel and the receptionist didn't recognize him. He started singing a bit of one of his famous songs right there in the lobby. The receptionist's eyes widened and he immediately upgraded Little Richard's room. It was hilarious how his music could have such an instant effect.
Sure! Little Richard was known for his flamboyant style. Once, during a concert, he started dancing so energetically that his wig flew off into the crowd. He just laughed it off and continued the show without missing a beat.
Richard Pryor had a hilarious story about trying to dance at a party. He thought he knew all the latest moves, but when he got on the dance floor, he ended up tripping over his own feet. Instead of being embarrassed, he made it into a comedy routine right there. He started doing these goofy steps and making jokes about how he was inventing a new dance style called the 'clumsy shuffle'. Everyone at the party couldn't stop laughing.
There was this time Richard Pryor went shopping. He saw a really strange looking hat and decided to try it on. When he put it on, he walked around the store imitating different characters. He pretended to be a cowboy, then a French artist. He had the whole store laughing, and in the end, he didn't even buy the hat but left everyone with a great story.
I'm not sure who 'Rae Lil Black' specifically is in the context of a detective story. It could be a fictional character created for this particular story, perhaps a unique detective or someone related to the mystery in the story.
Mostly no. While it might draw some inspiration from Lil Dicky's experiences, it's more of a fictionalized account with creative elements added for entertainment.
