@slaw---Yup, I watched the whole season of Cadillac Records, and was surprised it wasn't renewed for a second one. You can sure tell Martin Scorsese was involved, can't ya?! It really captures the New York attitude and energy, and the personality traits of people in the record and music business.
I had some issues with it in historical terms (just as I did with the TV movie Grace Of My Heart, a story about Phil Spector, Brian Wilson, and some other real life people, but done in a convoluted, mixed up way), but it was meant to be entertainment, not a documentary.
