"Isn't the main problem with the Mumfords that they are a bit, um, boring?"

Cringe...well they did want to add a light show ala Pink Floyd, but then they thought..."how very sixties that was" sorry to disappoint.

and punkfolkrocker. for some who professes to be indifferent and "not that bothered" you do rather go on a bit.

To each their own folks, I mean Mumford and Sons are exactly my cup of tea but they do have their fan base and they're fully entitled to it.
