I have just seen a 'Parky' show with the delightful Lesley Garrett. Apart from her marvelous voice, I was amazed at her vivacity and sense of humour. It was entertainment at it's best. Lesley was introduced as styling herself more like Gracie Fields than Maria Callas ... I'm sure she is truly loved for being herself.
If it wasn't for this type of show (and Parkinson show is the best of this genre) One would never see the other side of some of these celebrities, and we would be poorer for it.
It seems some people don't like the Parkinson show, these few people shouldn't watch it, especially when their jealousy for Parkinson's popularity shows so much.
