Now that Oasis have finally sorted themselves out, every festival on the planet's presumably got them on speed dial and let's be honest, Glastonbury without them would feel a bit incomplete at this point. The fact that fans are already mapping out what a reunion slot might look like tells you everything you need to know about how much people have missed them. We'll believe it when we see the official lineup, but if it happens, that's the kind of Sunday afternoon set that could define an entire festival. Either way, it's got to be one of the most anticipated "what if" conversations happening right now.
