Well... professionally... I have listened to one of his commercials... for about 4 seconds. After that, his face was a Pavlovian response to push the mute button.
However, he was a man doing a job (obviously good at it). By the accounts and stuff, he sounds like a decent, up-right guy.
I'm usually not one glued to such details, but there will be some interesting TV news over his and Michael's autopsies.
