Paul McCartney has released the third track from his upcoming Egypt Station album. The racy "Fuh You" has a chorus that sings "I just wanna fuh you," and was the sole track on the album due out on September 7th produced by One Direction and Demi Lovato hitmaker Ryan Tedder.

Paul recalled the process behind the new single: "With this one I was in the studio with Ryan Tedder whereas the rest of the album has been made with Greg Kurstin. We were just thinking of ideas and little pieces of melody and chords and the song just came together bit by bit. And then I would try and make some kind of sense of the story. So it was like 'Come on baby now. Talk about yourself. Tell the truth, let me get to know you' and basically 'I wanna know how you feel, you make me wanna go out and steal. I just want it for you.' So that was the basic idea and it developed from there. . . sort of a love song, but a raunchy love song. There you go -- fuh you."

With so many Beatles and solo classics under his belt, Paul McCartney admits that at times songwriting can be considered nothing short of divine intervention: "If you're lucky, songs are easy to come up with. The magic just happens quite quickly. Some of them, you've got to slog at; it's like anything. But the ones I feel luckiest with are songs like that. Something like 'Yesterday' really came without me knowing it. Y'know, I just woke up one morning, I kind of dreamed that melody. So, I mean, I was just lucky, I don't know really how that one happened. I haven't got an explanation for that -- except maybe this idea of a composer being some sort of vehicle that this (exaggerated voice) force flows through."

In addition to the lyric video for "Fuh You," McCartney also posted the teaser for his upcoming extended hour-long version of "Carpool Karaoke" coming to CBS' The Late Late Show with James Corden on August 20th at 8pm.
