[...] I downloaded the chipmunk .wav and recorded it onto my reel deck. After slowing it down and EQing it as much as humanly possible, I'd have to generally concur with your previous correspondent [Nathan]. The only place I might differ is on the last line, where the voice (to my ears) appears to be saying, "Sorry about that one." But with all the other noise going on, it could easily be "What was that again" as well. Whatever it is, it ranks as a major-league goof that some engineer should have caught (especially if the rest of can hear it). -------------------------

Thanks Mitch!
