Paul McCartney reveals how a 'happy' teen hitchhiking trip with George Harrison delivered a shock

Paul McCartney shared a humorous memory from his teenage years with fellow Beatle George Harrison involving an electric milk truck — and an unfortunate shock.

During a recent appearance on "The Rest Is History" podcast, McCartney reflected on a hitchhiking trip the pair took as teenagers while traveling toward Wales.

The 83-year-old musician said the experience later inspired part of a song featured on his upcoming album "The Boys of Dungeon Lane," which is scheduled for release later this month.
