The Foos pull out all the stops for their fourth Reading Festival headline slot, in a killer three -hour show full of every single one of the hits and (of course!) a Rick Astley guest appearance.
The Foos try and get Oasis back together, firstly with Taylor Hawkins' bass drum showing the faces of Liam and Noel Gallagher, and secondly with the drummer telling the crowd: “One of these days we’ll get Oasis back. One of these days." If anyone can do it, it's Taylor.
