"The Glastonbury Symposium was founded in 1991 by Roland Pargeter, who ran it for nine years. In 1999 the event was handed over to Sheila Martin, Andy Thomas and Karen Douglas. Karen moved on in the winter of 2004, and Andy and Sheila were then joined by Debbie Parkes. In 2008, Debbie was replaced by Di Brown to form our current organisational team. During the weekend itself, Andy and Sheila share the MC role while Di manages Front of House."
