Inspiration, have I tons...
Radio 2 first broadcast this fine documentary five years ago to celebrate David Bowie's 60th birthday. (01.05.07 REMINDER: BOWIE 60th RADIO CELEBRATIONS ROUND-UP)
They've tweaked a couple of things to bring it up to date and it's still a moving tribute with many great and very observant celebrity contributions.
You can read all about it in aforementioned news item, but if you can access the BBC iPlayer, set an hour aside to have a listen to a few great reasons as to why Bowie is still so important...as if you needed convincing.
