Music to "The Mighty Walzer" Book at Bedtime

[Proofraider]

Hi - can anybody tell me what the operatic music is that's being used at the start (and sometimes the end) of the current Radio 4 Book at Bedtime, "The Mighty Walzer" by Howard Jacobson? Have tried emailing the BBC but no reply from them, and I can't find any details on any Radio 4 pages. Thanks!
