This post, and the next one, contain things you'll have to pay for if you want to own. Not much money is involved though, and cash raised goes to charity, so stop your bloody complaining, right?
Packed full of goodness from The Son(s), Jo Mango, State Broadcasters, and Randolph's Leap, you can get the EP for £2 (or more if you wish) here.
My personal favourite is Randolph's Leap covering The Muppets. I love me some Muppets.
