Singer has enlisted Gaga for soundtrack to animated film 'High in the Clouds'
McCartney has already written seven or eight songs for the film, which is based on his 2005 children’s book of the same name.
Lady Gaga previously revealed the pair had been working together when she posted an Instagram picture of the pair – along with Pearl Jam guitarist Mike McCready – in the studio together.
“Had a beautiful session with Sir Paul McCartney and friends,” Gaga wrote alongside the photo, which also included a room full of instrumentalists. “Working on one of his many secret projects! Killer musicians, vibe, and lots of laughs.”
Gaga also posted a solo picture of her and McCartney and recalled how the pair ended up collaborating. “Always a good time with my buddy,” she wrote. “I’ll never forget when he called me last year to work and I hung up the phone cuz I thought it was a prank!”
High In The Clouds is being directed by Cody Cameron, who co-directed Cloudy With A Chance Of Meatballs 2 in 2013. According to the Guardian, it follows a squirrel’s anti-capitalist quest to find an animal utopia.
Meanwhile, McCartney has discussed his recent collaborations with rapper Kanye West, describing himself as feeling “lucky” and “flattered” to be working with the hip-hop star.
The unlikely duo collaborated on new music for West’s forthcoming album, with tracks ‘All Day’, ‘Only One’ and ‘FourFiveSeconds’ already unveiled ahead of its release.
Speaking to the Evening Standard ahead of his London shows this weekend, the former Beatle claimed to have been surprised that West wanted to work with him.
“It’s good to connect with different artists,” McCartney said. “The secret is I keep myself very open to suggestions – I still feel like I’m about 30.”
He continued, “I’m lucky that someone like Kanye would go, ‘Yes I would like to work with Paul McCartney’. I was quite flattered – I thought, ‘Why does he want to work with me?’ It was a few months later when I was starting to think, ‘should I ring him and ask him did anything come of the stuff we did?’ But then I thought ‘I can’t do that — that’s too soppy!’ I’ll just leave it and try and act cool.”
