Dolly Parton recently atteared at the huge out door Glastonbury Festival where she packed in over 100,000 people. Always one to never shy away from work. Dolly says she's never going to retire. The 68-year-old singer insists only if she or her husband Carl Dean got ill would she turn her back on her career and she hopes to keep performing well into old age. "I hope to continue to go, unless my health should fail me or my husband should fall sick. I intend to work till I fall over. I would love to be able to be like Bob Hope and Betty White and a lot of those folks that work till they're 90, 100 years old. I have no intentions of retiring!'' Dolly also admitted she loves seeing her friends ''slaughter'' her songs at karaoke. " I have seen my songs slaughtered pretty good, by some of my drunk friends. But it's always fun. It's always good.''
