Comeback bands Green Day and Blink-182 could headline next year's Leeds and Reading festivals.
The event's chief booker Neil Pengelly told Rock Sound that he had spoken to both bands regarding this year's bash but that next year would be a better fit for all concerned.
He said: "I think that Blink-182 will be doing something over here next year and I don't think we will see them here this year. I can't say what Green Day want to do but I'm sure they will reveal their plans in the course of time.
"We would love to have Green Day at Reading and Leeds one year and when they are around doing festivals then I'm sure we are something they will look at."
No rock day?
Pengelly also spoke about the lack of a heavy rock day in this year's lineup: "It was definitely a question and something we are conscious of as we booked the rest of the bill.
"We want to keep that appeal and be as broad as possible while at the same time getting the best bands we can. Once we announce the Lock-Up Stage people will see how rounded it is."
Green Day last played the event in 2004 and Blink-182 haven't appeared there since the year before that.
