How's about this for some heavyweight additions to this year's Arthur's Day line-up? Mumford & Sons, Primal Scream and Fun Lovin' Criminals are coming to bar near you soon, as news emerged this afternoon that the trio have signed up to appear as part of the black stuff's celebrations this 27th September.

Previously announced headline names include Example, Tinie Tempah, Ellie Goulding, Mika, Professor Green, Fatboy Slim, Texas and Amy McDonald.

No tickets are on sale for this year's performances, all you have to do is head to one of the 500 free Arthur's Day music events taking place across the country and keep your eyes peeled for who might walk in the front door!

Mumford & Sons' second album Babel will be released just days before Arthur's Day (24th Sept., to be precise) and the band will no doubt be in a rather celebratory mood.

Other acts announced as appearing include Rubberbandits, Delorentos, Royseven, Little Green Cars, Jerry Fish, The Hot Sprockets, Mundy and many more.
