The 34-year-old said he was “up for it” and John Lennon’s son, Sean, and George Harrison’s son, Dhani, had also shown support for the idea, although Ringo Starr’s son, drummer Zak, was less keen.
“Maybe Jason [another of Starr’s sons and also a drummer] would want to do it.
“I’d be up for it. Sean seemed to be into it, Dhani seemed to be into it. I’d be happy to do it.”
James said that the idea had already been mooted “a little bit”.
Asked if a new Beatles could happen, he said: “Yeah, hopefully, naturally. I don’t know, you’d have to wait and see. The will of God, nature’s support, I guess. So yeah, maybe.”
The singer-songwriter, who’s played guitar on two his father’s albums Flaming Pie and Driving Rain, is following in his father’s footsteps by playing a gig at Liverpool’s famous Cavern Club on Tuesday.
The Cavern is where the Beatles played dozens of gigs before hitting the big time.
James said is had been “beautiful” working with his father, who co-produced two of his EPs, including sessions at the Abbey Road studios.
Asked about his relationship with Sir Paul, he said: “It’s amazing. Sometimes in the past, a few years ago, it can be difficult, it can be tense, like families can get.
But beyond that it’s beautiful. “He’s a genius, he’s beyond genius, and he’s a big inspiration. Very intellectual and obviously amazing at what he does, so it’s great fun.
James admitted that having the name McCartney was “a help” in the music business and it was “an honour” to be connected to his father.
He said that as a schoolboy he’d dreamt of “being better than The Beatles”, adding: “I’m not sure if I can do that. If anything, I would love to be equal to The Beatles – but even that’s quite tough.”
All of the Beatles boys have taken after their fathers. McCartney has played guitar on two of his father’s albums, and is playing a show at the Cavern Club in Liverpool, where the Beatles cut their teeth.
Starkey has drummed for the likes of The Who and Oasis, Harrison is the frontman of thenewno2 and Lennon is a successful singer-songwriter in New York.
