More Sheen

Piers Morgan will need to hunt down more stars on the brink, if his CNN show is to overtake Rachel Maddow at MSNBC on a regular basis.   The Charlie Sheen interview on Monday last week recorded 561,000 viewers in the US 25-54 year-old demographic, giving Piers his highest figure since the opening Oprah interview on January 17.   Then, I'm afraid, it was back to business as usual.
