Found it!
James Last - "Biscaya"
It's not much that I was successful in identifying, but I've bumped into program named
Tunatic.

It is free, and identifies songs you play on your PC or from some other source simply by melody! Amazing! This is an instrumental with no tags in mp3 file whatsoever, and
Tunatic identified it in few seconds!
Hope some of you might find this info useful.
