Virgin Records co-founder Richard Branson is trying to fix his son up with a girlfriend - and he's even considering starting his own dating service to help out. The British ideas man was a guest on U.S. lifestyle queen Martha Stewart's daytime show Martha last week (ends12Oct07) when he tried to desperately find his musician son a date. He said, "I've got a son who's a musician. He's 21 - good looking girls, single, available." He then added, "Virgin Dating - sounds good."
