The former Beatle revealed his admiration for the psych-pop duo, and said that if they rang he up he would be happy to collaborate.
He added: “We need to talk about it. I can’t call them. If they called me, I’d say, ‘How did you get my number?’. But I’d do it.”
McCartney also spoke about his much-talked about possible collaboration with Bob Dylan.
“So much has been written about me doing a collaboration with Bob or me doing a collaboration with Ringo and Bob,” he said. “But that is not happening yet. We’re nowhere near.
“I did say I wanted to work with Bob but that was ages ago and he hasn’t been in touch. I can’t contact him. That’s not cool.”
He then jokingly rapped, “Hey Bob, what’s happening? Where’s the party?”
