Rolf Harris caused a serious nuisance this year. For some reason they put him on the Jazz/World stage instead of the Pyramid(main). Which resulted in nearly the entire audience at the festival trying to trek from the main stage(and elsewhere) to Jazz, which resulted in the most atrocious congestion. Tastes may change over the years, but dear old Rolf is still the most compelling crowd puller, especially as he covers all age groups(everybody who has ever been a child, basically).
