Frank Black has a son. Here's the story from undercover.com:
Pixies frontman Frank Black has become a first time father. Black (whose real name is Charles Thompson) and partner Violet, became the parents of Jack Errol Thompson on January 7 at 3.59pm in Springfield, Oregon. According to Black, "He's perfect and 7 pounds and 9 ounces of pure handsome".
The picture they show of the Pixies is slightly outdated. They all have hair, and Frank Black looks like he's about 7 pounds and 9 ounces. Also, I'll bet that baby can scream.
