Do pick this up, even if you've only a passing interest in Bowie. In their own words:
A couple of years ago we released an audio drama called 'Vince Cosmos: Glam Rock Detective,' written by Paul Magrs and starring Julian Rhind-Tutt as Vince. It was Paul's silly love letter to David Bowie, supposing that Ziggy Stardust really was an alien. But of course, he wasn't, and today we all realised that Bowie was just as human as the rest of us. So by way of tribute, we've made Vince Cosmos available to download for free at the link below.
Nice of them, and I have seen Paul Magrs promoting this as well. It's a good story funny and melancholy and just odd at times - you know, like a Paul Magrs thing, only not quite like anything else he's written.
