Michael Eavis had admitted that it was "a bit of a mistake" that the Wombles are booked to appear at this year's Glastonbury festival.
Festival founder Eavis expressed his concern that the Wombles will play the Avalon stage on June 26, reports BBC News.
"I've got about 25 stages and managers and bookers for each of the stages. I can't control every single one of them but I do get cross about that kind of thing," Eavis told BBC News.
Glastonbury will be headlined by Coldplay, Beyonce and U2. Tickets have already sold out.
