NME speaks to Catfish And The Bottlemen's Van McCann in London about the announcement of Mumford & Sons playing Reading & Leeds festival and their upcoming headline slot at Brixton Academy. Watch the frontman discuss why he doesn't care if the band's compared with Oasis or called out for sounding 'dated';' the 'enormity' of the Brixton shows and what to expect; and why it's cool Mumford & Sons are headline Reading & Leeds because festivals are supposed to divide opinion and, actually, Mumford & Sons are way more rock 'n' roll than you'd think; and why he only likes The Streets.
