Sad to know Chilly Billy passed away last week.
Thankfully, I think you can still see some of his cuts online. When you do, you'll see a very smooth and friendly character. I mean really smooth. If you feel you're saying "uh" or "um" too many times on the air, take a look at the old Bill Cardille bits and try to model your pattern of speaking after him.
What I find impressive about him is that he does perform a very funny character without becoming a clown, and that's not always easy to do. You could go from seeing him do a corny skit one time, but then still trust him to give you the weather on the news. Again, like I said, really smooth.
Pittsburgh has lost its greatest living broadcasting icon.
