A saucy dance troupe will be adding a little 'je ne sais quoi' to the UK's biggest rock festival this weekend.

If you thought Glastonbury was all about long-haired rockers and mud - think again.

The women, who call themselves Les Ooh La Las, will be high-kicking three times a day at British music's holiest site.

By day, the women work in shops and offices. But at night, they turn into squealing, pouting, dancing girls in bodices, stockings and frilly knickers.

Catherine Senger, a subject co-ordinator at the University of Sussex, joined Les Ooh La Las last year. She said: "Can-can dancing is good fun, it is exercise and it is also quite daring. It is exciting being on stage throwing your legs about in French knickers, stockings and a tight corset.

"It is both sexual and sensual and appeals to everyone. Everyone knows the dance and the music is familiar. The costumes are also quite flattering - feminine but earthy."

The seven-strong group began dancing together 18 months ago and were given a leg-up with the release of the film Moulin Rouge starring Nicole Kidman and Ewan McGregor.

The troupe dance at parties, restaurants and festivals. They strutted their stuff at the opening of the Pussy Cat club in Hove and they have paraded on the Palace Pier.

Traditionally can-can dancers were not a chorus line but cheeky individuals who danced to get attention.

Cathrine - stage name La Desse - said: "We are trying not to portray the stereotypical chorus line of girls who all look the same and are the same shape and height.

"Like the original can-can dancers, we are all shapes and sizes and ages and full of character."

None of the women is a trained dancer and the choreography is a joint effort.

The women, who are dancing to Offenbach's Orpheus in the Underworld, could find themselves rubbing shoulders with bands like REM, Radiohead, Moby, David Gray, the Manic Street Preachers and Fatboy Slim who are all due to appear in Somerset.

The other women putting oomph into Les Ooh La Las are Thrse Endette, Ruby Woo, Belle Noire, Foxy, Joanna La Lune and La Fe Verte, all of which are their stage names.
