KNAK shout-out in "Salt Lake City"

[bonnevillemariner]

If you listen closely to the original 1965 mono version of "Salt Lake City," it seems like somebody yells the call sign for KNAK, their flagship station in SLC, at about the 30 second mark.  I can't quite make out whose voice it is.  I don't hear this call-out in the 2001 stereo mix.

a) Can anybody confirm that KNAK is being shouted, and

b) Does anybody know why it was edited out (or buried to the point of inaudibility) in the 2001 stereo mix?
