I went to V Festival to see Oasis in 2009. They didn't turn up due to Liam being sick. They broke up the following week. Thankfully, the main reason I was there was to see 'James' play, but Snow Patrol made the festival at the end as a headliner to replace Oasis.
Went to the first one in 1996. Pulp headlined, Supergrass, The Charlatans, Gary Numan, Shed 7 on the main stage. Better days. Not nearly so commercialised as now either.
I went donkeys years ago when Paul Weller headlined. Rubbish, overly commercial and a rammed full of oiks who all seemed to be rushing around everywhere and who wouldn't know a festival if it smacked them in the face. Hideous.
