Guess the name of musician

Two men got out of their cars after they collided at an intersection. One took a flask from his pocket and said to the other, "Here, maybe you'd like a nip to calm your nerves."
"Thanks," he said, and took a long pull from the container. "Here, you have one, too," he added, handing back the whiskey.
"Well, I'd rather not," said the first. "At least not until after the police have been here."
