"Hello Earth" Kate Bush/ Choral Group

[Delbert Stanley <dgstan@earthlink.net>]

Hello Kate Bush fans. I saw a TV segment of "Miami Vice" that featured
Kate Bush's track "hello earth". In one scene the background music was
that choral group that is included on this track. Some sites that show
the lyrics simply describe this group as a Czech or Russian choral. Does
anyone identify this group.? Record labels, CDs etc. I saw a PBS
documentary about the Trans Siberian Railway that I believe included
this group as the railray past Lake Bical? I wrote PBS, but they could
not provide the information, and no credits were listed. On KB's "Love
Hound" on which "hello earth" appears, she gives credit to "Youth", but
I'm not sure if this is what I need. Using "Youth" in a search engine
can be overwhelming. I would appreciate if anyone could identify the
choral group on "hello earth".
