Marcus Mumford denies 'Babel' symbolises Mumford and Sons' Christian faith.The frontman - whose father was a vicar - insists the album isn't a statement of their religious views and the band are more driven by ''spirituality''. He said: ''The LP is not a statement of faith. We don't feel evangelical about anything, really, other than music. ''I don't even call myself a Christian. Spirituality is the word we engage with more. We're fans of faith, no religion.'' The 'Little Lion Man' singer also clarified his lyrics to 'Whisper In The Dark', which reference God. He explained to Big Issue magazine: ''The lyric, 'I set out to serve the Lord', no-one realises it's pluperfect tense. ''The lyric is 'I had set out to serve the Lord'. It's looking back at a time when that happened.'' The band - also including Ben Lovett, Winston Marshall and Ted Dwayne - announced their latest arena tour earlier this week, and admit they are nervous about headlining such huge venues. Winston said: ''We've only ever done five [arenas] I think. ''We did three in Canada, one in Portland, Oregon and one in Amsterdam and it was quite difficult. ''Big respect to bands who do arenas because, it's a big space to fill.''
