Organisers of the Royal Bath and West Show have unveiled new events for this year's event - their 150th anniversary.
Glastonbury Festival founder Michael Eavis is going to be putting on a 20 minute show in the main arena to help them celebrate.
He has got involved because his family have been farming nearby for 148 years - just two years less than the show itself.
He is keeping the details a secret but says it will be a typically wacky, Glastonbury-style spectacle.
The show is taking place at the Royal Bath & West Showground at Shepton Mallet from 29 May - 1 June
