MUSIC / Upbeat: Coda

NEVER, ever, do you have official advance word of the chosen pieces for Desert Island Discs - especially when the castaway is David Mellor, as Radio 4 has with impeccable timing decreed for next week. So you will have to have your fun speculating in the meantime. Will the former London Philharmonic board member go for, say, the orchestra's version of Between Dusk and Dawn, by Sir Arnold Bax, or the Saint-Saens Organ Symphony? Or will he play safe with Delius's Over the hills and far away? Not long to wait: first broadcast is due at 12.15pm tomorrow.
