Query: Not Sir Thomas

Just chiming in to say that this is definitely not the Beecham performance. I own the Beecham on a set of Melodram LPs out of Italy, and just listening to the opening bars would convince anyone that these are different performances. And, of course, there is no mistaking Welitsch's distinctive voice. The LPs, by the way, all things considered, are quite decent sounding and without significant technical lapses.
