Something which has always puzzled me about this track, and it says it uses elements from planet of the apes, is this parts of the soundtrack or just background noise, as it’s credited to Jerry Goldsmith....? Has anyone know the answer to this?

As far as I remember, the only sound bite that was sampled from the soundtrack is the two high notes you can hear at 0:25 and than later in the song:



Unfortunately I don't know from which song it's taken, I recognized the sample watching the movie years ago

Thank you for that!
