"Hello Earth" Choral group

[Delbert Stanley <dgstan@earthlink.net>]

I saw a Miami Vice episode that featured Kate Bush's "Hello Earth"
track. On that track there was a male choral group accompanyment. I
cannot identify who this group is or other recordings they may have.
Other usenet sites describe this group as "a men's choral passage in
either Czech or Russian". I saw on PBS about two years ago a documentary
on the Siberian Express Railway. As the train passed Lake Bicol the
background music seemed to be the same group that appeared on KB's
track. Can anyone identify?					

I hope I am doing this correctly. This is my third time online and first
time to send E-mail to a newsgroup. Pardon my lateness, I realized the
track was first recorded in 1985
