1983 called for a licence to be obtained for the event since the introduction of the local Government Act became law, giving local authorities the power to regulate such events by stipulating the conditions.  Mendip District Council issued a Public Entertainment Licence which set a crowd limit of 30,000 and went into considerable detail about access roads, water supply, hygiene and so on.  It was also the first year that the Festival  had its own radio station, Radio Avalon. £45,000 was eventually raised for CND and local charities.

Acts included: Marillon, The Beat, UB40, Curtis Mayfield, King Sunny Ade.

Attendance: 30,000. Tickets:  £12. Programme price:  50 pence.
