In 1969, Paul McCartney sat down in the house on Baskervyle Road, Heswall, he had bought for his dad five years earlier, for £8,750.

Opposite him was radio presenter Roy Corlett, who had attended the Liverpool Institute with Paul, and fronted a Radio Merseyside show called 'Light and Local'.

The title makes it sound frivolous, but Roy's interviewing style is relaxed but also pretty tough in its own way. For Beatles fans - and pop culture historians - it's an interesting 15 minutes of airtime.

Paul McCartney talks about The Beatles' retreat from performing, saying what more can you do when you've played to 56,000 people at New York's Shea Stadium (in 1965)?

He talks about his recent marriage to Linda Eastman and "a ready made family", and his collaboration with John Lennon, saying that when his sentimentality met Lennon's 'harder' instincts, the results were what has become the extraordinary Lennon and McCartney songwriting legacy.

Of John Lennon and Yoko Ono, he observes that, while he felt deeply for abandoned Cynthia Lennon, he could not dispute that John and Yoko were very much in love and right for each other.

He is also obliged to mount a spirited defence of 'Magical Mystery Tour', The Beatles' hyper home movie that aired at Christmas on the BBC in 1967 - and was met with an underwhelmed reception by both press and public. Paul argues that the colour film should never have been broadcast to black and white TV sets, and that this caused confusion.

The conversation is worth a listen - giving insight into the mind of a 27 year-old who, along with three bandmates, had conquered the pop world, but was resolved to become an even better and more influential musician.
