The creators of The Muppets and Sesame Street are staging a puppet show that is strictly for adults only.


Miss Piggy would blush over the antics in "Jim Henson's Puppet Improv" which spearheads a renaissance of puppet shows for grown-ups at this year's Edinburgh Fringe arts festival.

Every afternoon at the Fringe, an anarchic troupe of puppeteers led by the late Jim Henson's son Brian do an improvisational show for kids.
