Unknown Trance tracks from 1994 or before

[spiiidey]

Hello,

the following trance tracks are all from a tape of 1994.
I hope one of you will be able to help me finding out more
about the titles or artists:

This one could be called "It's the ultimate".
The lyrics are: "Can you feel it, feel the rhythm of the ultimate"
zSHARE - 1.06 It_s The Ultimate.mp3 (http://www.zshare.net/audio/523518466da17035/)

The title of this one could be "Revolution", it's the only lyric.
zSHARE - 1.07 Revolution.mp3 (http://www.zshare.net/audio/523522362aad90b2/)

I have no idea about this track:
zSHARE - 1.08 Track08.mp3 (http://www.zshare.net/audio/52352354c5a46fc6/)

This track sounds like a remix of Alan Parson's "Sirius" and a there's a woman's voice saying "Mastermind":
zSHARE - 2.06 Mastermind.mp3 (http://www.zshare.net/audio/52352584589f00f9/)

Short part of another unknown track. It sounds like the cover of a well known disco song from the 70ies, but I don't remember it's title.

Thanks to everyone in advance
