I realise that this is a long shot, but the BBC's recurring TV advert for the Radio 4 Proms broadcasts uses the famous 'Ode to Joy' extract from the final movement of Beethoven's 9th symphony. Can anyone recognise this as being from an available recording of the symphony? I guess the LSO or BBC Symphony Orchestra would be the most likely, though I appreciate the difficulty of identifying on the basis of a roughly 10 second extract!
It is almost certainly from one of the BBC's no doubt many inhouse recordings, for the simple reason that they already own the reproduction rights. Sadly for you this is unlikely to be available as a commercial release.
