Reading Festival will never be jollier than in the back-to-back blast of ‘I Will Wait’ and ‘Little Lion Man’, two songs that encapsulate the most loved and loathed sides of Mumford & Sons. Impassioned banjo-led brodowns are easy to diss on record. When it’s here, in the company of thousands, it’s impossible to resist. Ted Dwane - up there with Este Haim in the bass-face stakes (double bass-face?) - is having the time of his life, and it’s almost like third album ‘Wilder Mind’ never happened.  Things are brought back down to earth with a thud. Nothing tops Mumfords’ most-loved in their Friday night headline set in terms of sentiment or enthusiasm - this time round, the banjos win.
