I recall reading that the Russian soprano, Elena Ruszkowska, soprano was
later Elena Ruzicka, alto and appeared on record labels with the latter ID
(or similar. I'm not where I can see the records at the moment- snowbound.)
She shows up in some of those extended excerpts sets and duets. Can anyone
confirm or debunk info along these lines, one way or the other?
