Dolly Parton worried about the crowd looking up her skirt at Glastonbury.

The '9 to 5' hitmaker played the festival for the first time this year and took great care with her outfit, deliberately wearing trousers because she knew the stage was high enough to expose her ''contract''.

She said: ''I wanted to wear pants because the stage was up so high, I didn't want the crowd looking up my dress and seeing my 'contract'.

''And I wore white because I feel light, airy and happy when I wear white. And I didn't get dirty. Even in all that mud.''

Dolly, 68, admitted she was gripped with nerves before the performance because she was convinced her songs wouldn't go down well with a ''rowdy'' crowd.

She told Britain's Glamour magazine: ''It was nerve-wracking because people kept telling me how big a deal it was.

''I was worried it was going to be ore of a rock crowd and I wasn't going to fit in.

''I spent a lot of time deciding what songs to sing because I was led to believe these people were rowdy, stoned and drinking, so I couldn't sit down and sing a lot of sad songs.''
