Happy Birthday! (Hope you're able to listen to some great music, read a great book, watch a great film - well. maybe not all in one day - and enjoy life.)
I've always thought that it would have been interesting to hear where that band would have gone if Miles had kept it together for a while. Didn't happen, so it's all speculation.
Do you know how sometimes you put a recording on the box and the music is just right for the way you're feeling? That's how it was with this one earlier today.
