Joan Van Ark, Michele Lee and Donna Mills recently got together at the Hollywood Bowl for a fundraiser promoting classic music, which was hosted by The Jose Iturbi Foundation.  The Knots Landing trio revealed that they still maintain a close friendship.  “The truth is that we are, in fact, sisters,” said Van Ark.  This December marks the 40^th anniversary of the nighttime soap.  While the ladies hope for some sort of reunion special, they have another idea.  “A show that we were going to call We’re ‘Knot’ Done Yet,” says Van Ark.  “And we’re not.”
