Paul McCartney talks about the White Album tracks

Published June 25, 2017 on Youtube, here is a 1968 interview with Paul McCartney, where he comments on the tracks on the then new, self-titled Beatles double album release.
The interview was done by an Australian radio announcer, Tony MacArthur, who had a regular Beatles Show on Radio 4BC in Brisbane during the late sixties and early seventies.

Although mainly covering his own compositions (after mentioning that it was for Lennon to comment on his own songs), Paul did mention Lennon’s “Happiness is a warm gun” and “Good night” (sung by Ringo).
