It's been a rollercoaster of a few months for West London's folk rockers, Mumford & Sons. They've headlined Glastonbury in June but had to deal with bassist Ted Dwane's terrifying blood clot health scare that required immediate brain surgery and several cancelled US festival appearances. Dwane rested until Glastonbury Festival when the quartet resolutely took to the stage armed with their banjos, mandolins, guitars, and even a brass section to show the world the Little Lion Men were unstoppable. They played a barn-storming headline slot, blasting their hits with defiance and making the entire Vale of Avalon take notice.

Mumford & Sons Now Back At No.1 After Glastonbury Success.

Such was the success of the Sunday headliners that many in the crowd were converted to Mumford & Sons' distinctive banjo-tickling ways and rushed home to purchase a copy of their most recent album: September 2012's Babel, despite lead single 'I Will Wait' having premiered nearly a year ago. The album has enjoyed 40 weeks in the charts but Mumford's festival success induced a 384% sales increase, propelling the 12-track record up 15 places to the No.1 roost in the week following the festival and beating Michael Bublé's To Be Lovedby just 125 copies, according to The Independent. Their 2009 debut Sigh No More also climbed to the 12th place after their sunny Somerset hoedown.

Other acts to benefit from a post-Glastonbury push include Tom Odell, Arctic Monkeys, Jake Bugg, and The Rolling Stones in a festival dubbed as "the greatest Glastonbury ever" due to a strong line-up and warm weather after Worthy Farm's 2012 year off. Mumford & Sons have the current No.1 album whilst John Newman's 'Love Me Again' currently tops the UK singles chart
