Not this year but festival booking agent hints that discussions are open with both bands.
Rock Sound interviewed Reading And Leeds 2009 head booker Neil Pengelly and he hinted that Green Day and Blink-182 may be lined up for the 2010 version of the festival:
''Of course we speak to all the best bands each year. 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.''
