Paul's Future Plans in an August, 1966 Radio Interview

There was a radio interview by Keith Fordyce of Paul and John called The Lennon McCartney Songbook that was recorded at Paul's home--7 Cavendish Ave.--on August 6, 1966. The full interview can be heard at:  www.podcastdirectory.com/podshows/2270583. 

The relevant part of the interview came at 22:48-23:04 in the recording when John and Paul are discussing their songwriting:

     John (with humor in his voice):  I'm just finding I don't know enough chords to write them [their songs] in
                                                    guitar, so I'm going to have to get some old fella in to play to me.
    
     Paul:                                        It's got to be an old fellow, though.

     John:                                        Yeah.

     Paul:                                        Couldn't be one of these young, whiz-bang kids, you know.

     John:                                        HE WOULDN'T HAVE TIME.

The replacement for Paul was seven years older than Paul as was dramatized in the 1967 Beatles' Christmas record.  And John's comment shows that, one way or another, Paul was leaving the group.
