Other performers included Thomas Dolby, Cutting Crew, Limahl, Kim Appleby, Nik Kershaw, Go West and Midge Ure.

Scores of people got into the festival spirit by dressing up for the occasion, with Star Wars characters and bright pink flamingos blended in the crowds.

The family-friendly event also included plenty of activities for youngsters at Kids' Kingdom, with an interactive circus, face painting and inflatables.

Thousands are expected to return to the park for the Sunday Sessions concert to watch headline act Noel Gallagher perform with his band High Flying Birds.
