'Hound Dog' took like twelve minutes. That's not a complicated piece of work. But the rhyme scheme was difficult. Also the metric structure of the music was not easy. 'Kansas City' was maybe eight minutes, if that. Writing the early blues was spontaneous. You can hear the energy in the work.
If you don't have a story that will hold the audience, you won't have a successful show.
Sure, I suffered a lot. But it's not like the end of the world and it's not who I am. I lead quite a pleasant life and I'm able to divorce a perceived reality from my actual experience of life.
