SAS - Amber Groove - Version without vocals??

I've got what sounds like SAS - Amber Groove on tape somewhere, but I'm sure it doesn't have the vocals
Maybe it was mixed out before the vocals come in, but I was wondering if anyone knows of a version without vocals?
I've not been able to find anything
Thanks!

I think it's the "Respect To The Brook mix"

Thanks - yeah, I wondered that at first, but it's quite a bit different that mix.
I guess my tape either cut in after the vocals, or mixed out before them
Or I just didn't notice the vocals!

Sometimes I think I've found a track, then later realise that there's another very similar one with a totally different name!
