> if Paul responded, it was edited out.
I believe that the response was captured in the 1969 glossy photo book that accompanied the Let It Be release, credited to Jonathan Cott and David Dalton. The entirety of it:
George: Are we getting an 8 track?
John: Phone America, they're quick
Glyn: They've only got 4 track
Paul: I know they got the 8 track out for The Beach Boys. (Texan voice) 'n if they got it owt fer the Beach Boys...
...and then George changes the subject by singing a little of All Things Must Pass
