wait a minute...I listened again for a third time..but this time all the way up and yes you are right it's there..I find that to be amusing thanks for pointing that out..Most likely it was someone maybe one of the producers listening in to the recoding and one of the mics picked them up. The reason why they took this take is because you can't notice it unless you have the music turned up all the way and it only happens for less then a second. I would have kept the recording as well because it is not only time consuming but it is also not cheap to do a recording..Anyways yeah thanks though for using your high listening skills..I'm surprised I did not pick up on this sooner but then again I rarely have my music blaring..I like my ears!
