Mumford & Sons have announced a "groundbreaking" world tour.
The 'Guiding Light' singers will perform to 800,000 in 60 shows, starting in Dublin on 16 November - the day they release new album 'Delta' - travelling through the UK until 2 December, where the first leg ends at Liverpool's Echo Arena.
They will then jet off to North America for five shows before Christmas and take a short break before hitting New Zealand and Australia in January and then returning to the US and Canada for more shows between 27 February and 31 March.
The 'I Will Wait' hitmakers will take almost four weeks off before closing out the lengthy concert series with 15 European shows, beginning in Barcelona on 27 April and ending on the 21 May in Stockholm.
The gigs will take place on a "new groundbreaking stage right across the middle of the room", and are the biggest shows they have ever played since forming 10 years ago.
And the quartet - Marcus Mumford, Winston Marshall, Ben Lovett and Ted Dwane - have teased they will be adding more shows to the "extensive and ambitious" tour.
They wrote on Instagram: "Announcing the #DeltaTour - the most extensive & ambitious tour we've ever done. Travelling the world & playing shows was our initial, and remains to be our primary, purpose as a band.
"The Delta Tour is going to be everything & we are going to leave it all on the floor.
