This Thursday the Walton Chamber Orchestra will make music history when it becomes the first ensemble ever to perform in the Underwriting Room at Lloyd's of London. As if to prove that Charles Ives was not the only composer ever to have made his living from insurance, the concert includes not only the Lady Radnor Suite by former Lloyd's underwriter Sir Hubert Parry (better known as the composer of that Last Night of the Proms standard, Jerusalem), but the premiere of a new work, Encounters, by current Lloyd's underwriter, Rodney J Stone.

With a suitable sense of occasion, Stone (who, in a Heckler-deterring move, bills himself as 'a composer of modern understandable orchestral music') has not only set one of his own wife's poems to music - alongside texts by Philip Harris and Lord Byron - but has incorporated into his score the unique sound of the Lutine bell.

Members of loss-making syndicates will no doubt have their ears peeled to count the chimes: for, as all Lloyd's names know, one ring of the bell means a ship's lost at sea, two rings of the bell mean it's safe home to harbour.
