Audiotrack 6A & Pink Floyd

So I was reading the Happy Cycling page last night and saw that "Heart Beat, Pig Meat" by Pink Floyd is listed as a constant sample throughout the track. While I wasn't really that good hearing how it was sampled, I did notice something else. However if somebody could point out to me how it's sampled in Happy Cycling that would be nice.

There isn't much to say really, just listen to the Pink Floyd track first then Audiotrack 6A below it. Note that, among other instances, the voice at 1:32 in the Pink Floyd track can be heard in the BoC track as well (just in case you had doubts)

So that's actually pretty cool.
