Sue Barker was somewhat overshadowed by Wade, and the British press, then & now, piled the pressure on her and her nerves were brittle at the best of times. That said, when 'on' she was a joy to watch. She was also stunning to look at, which actually probably didn't help as this also gave her considerable media attention. Interestingly, whilst rarely troubling Evert (although she did beat her) she gave Austin fits. And now she's a very successful, and popular, presenter for the BBC so it's all worked out for a lady who seems very genuine & likeable.
When ever I read "PTL" I'm reminded of 'Deliverance'.......bad teeth, & a banjo....
