It's funny how this guest stars thing goes. I watched another two episodes of Hart to Hart today and didn't spot anyone from Dukes. I didn't recognize any of the guest stars in the first episode ('Murder Between Friends'). The second, 'Cop Out', featured Burr DeBenning who was in a couple of episodes of CHiPs and The Fall Guy. It also had an early appearance of Markie Post who went on to be Terri Michaels in The Fall Guy. The Terri Michaels character basically took over from Samantha 'Big Jack' Jack who was played by Jo Ann Pflug (Helen Hogan in 'Route 7-11') - that's the closest I could get to a Dukes connection!
