Strange noises while playing footie

Hello people, 2nd post on here but a long time following this forum. Anyways onto my little story.

To start with my name is Kelvin, just your normal average Bristolian.

Now, my cousin (Zach) comes up every saturday pretty much maybe missing the odd one or two but pretty much all the time, we both like football and we both consider ourselves pretty good. So we decided to make a video showing some tricks and then put them on the internet. Whilst making the videos we picked up two strange noises the first one being a scream and the second we don't know to be honest. The first one is just a scream but the second we can't quite make out, it sounds like me saying f*** you quickly followed by what sounds like the same person/thing doing the scream but making another noise like it was in distress. I didn't say f*** you, well atleast I don't think I did. I mean why would I recording a football video ?.
This was at about 8pm to 9pm at night in October 2007 and there were no other people around us as we checked after.

Anyway I will let you make up your mind on what it is, could of just been a person but we thought it was strange so posted it here.

Attached are two audio recordings taken from my cousins camera phone (they were actually videos but I have turned them into audio for easier access).
