4 unknown please help!

They are all various styles but I thought I post them toghether anyways since shirt.mp3 is the most recent one and it is upfront house.

Some info:
chem98.mp3 : Was played by The Chemical Brothers backstage in the VIP area of Glastonberry Festival in 1998. Kinda breakish and hard to describe, most likley a remix from a rather commercial track.

fsol.mp3 : Was originaly requested by another person, but I thought it was such a great track (being the fsol fan that I am) that I thought I start a hunt myself too. Apperently it is from a 12 hour set by fsol in the mid 90s.

shirt.mp3 : Played by Deep Dish on 102fm on 2004-11-25. I have not found a tracklisting anywhere.

sven.mp3 : From a double 12" (have it as mp3 only) that says ´"Sven Väth - Unknown (Aural Float Mixes). The first track is indeed the Aural Float Mix of Sven Väth - The Birth Of Robby. The third track is Barbarella - The Secret Chamber Of Dreams. But what is this second track? The info on the mp3 release says 2002 but it was more likley from 1992 or around there.

These four and a fifth (no sample) from a NetMix set by Mr C from 1998 witch was kinda bouncy trance with a chopped vocal going "a da da da da daaa" and some bleepish synths (possible a trance/dub remix of a Deep Forest track, sure sounded that way atleast) are my only unknowns.

Any help would surely be appriciated!
