You can find an archive of the On the Wire show where Steve Barker played Grievous Angel’s re-rub of Niney the Observer’s Blood and Fire here.
It’s very low res and so the quality isn’t all that but it’s OK — it’s the last of the jungle tracks (The Bug, Kid 606, Congo Natty… great company), at the front of the show, before tunes by Ijahman Levi and Tubby. Steve introduces the tracks at around the 36minute mark.
As you can imagine, my first play on the radio is a very proud moment for me :).
