As part of Pull Out All The Stops, the Royal Festival Hall's celebration of the restoration of their organ (I joke not - no penicillin involved), Pete Flood and Andy Mellon have been working with local children (Southwark schools) and animals (the Voicelab Choir) on some really off-the wall pieces involving four organs inspired by Heath Robinson. The program, Wondrous Machines, involves half of Bellowhead as well, so if you fancy some free bellowing, our heads having been blown away some time since, come along. And if you can't make it, I am told we get a bit more of our fifteen minutes of fame on Radio 3, most likely The Choir on 23 Mar.
