I was listening to Eurobeat Flash vol 22 when I heard this at the beginning of Vicky Vale - Love Child:

It's a weird thing to start a song with. But I'm very familiar with this kind of sound. If you have a reel-to-reel tape player, you'll know that this is what you hear when you rewind a tape and leave the Repro button on.
I knew if slowed down to just the right amount, you would be able to hear what was on the tape (though not clearly, there is a lot of high frequency loss when you attempt to slow down something that was recorded at a fast speed).
So I reversed the sample, and slowed it down until I heard something that sounded like a slow bass guitar and (tonewheel organ/monophonic synth?) melody. Keep in mind that I don't have any sophisticated software that stabilises playback speed, so the speed fluctuates throughout the sample:

So this is what I think I heard.....
0:00 - 1:15: Drums with some bass guitar, ends with a cymbal?
1:28 - 1:57: Short burst of drums and a male voice, then mains hum (prob. from a guitar amp)
1:58 - 4:23: Instrumental rock music!!
4:23 to end: Faint male voice singing & instruments, maybe an organ? Makes me wonder if this could be a multitrack tape and what we're hearing is track "bleeding", when a channel on a multitrack tape is picked up on another channel.
Maybe this is a jam session from one of Sinclaire's old tapes

Has anybody here discovered an easter egg or come across just a general oddity in a eurobeat track?
