I take it that's written by Melissa who started up the Pottercast podcast? I used to love listen the that one and Mugglecast, and even spoke to Melissa over Skype once on one of the phone-in podcasts (although they were having tech problems so it never made it into the actual podcast )
Funnily enough, my mojo's gone for a Burton these last few weeks, but today I started listening to Stephen Fry reading Harry Potter and the Deathly Hallows as I realised I'd only read it once, and can't actually remember much of what happens!
