Paul McCartney reckons that he saw God while tripping on DMT and, in a completely separate non-DMT assisted incident, gave Stormzy a quick tutorial in composing when the rapper asked him for help to expand his skills.

Macca remembered taking the hallucinogenic while still in the Beatles with, among other people, the gallery owner and art dealer Robert Fraser in an interview with the Sunday Times.

"We were immediately nailed to the sofa. And I saw God, this amazing towering thing, and I was humbled," McCartney recalled.

“It was huge. A massive wall that I couldn’t see the top of, and I was at the bottom. And anybody else would say it’s just the drug, the hallucination, but both Robert and I were like, ‘Did you see that?’ We felt we had seen a higher thing."

Macca also said that on another trip he was "thrilled" to see a white squirrel which he took to be his late wife Linda, who had come to give him a message.

The former Beatle also said that Stormzy had asked him for some pointers on how to compose on the piano.

"He’s looking to advance his music. As a rapper, I thought he’d have words down, but there was a piano, so I showed him basic stuff — how you get middle C, make a chord, a triad and, just by moving that, get D minor, E minor, F, G, A minor, and how that’s enough for anyone."

It's not as unexpected a pairing as it sounds. McCartney's a hip hop fan, as his interview with Jarvis Cocker at the Liverpool Institute of Performing Arts last week showed: he picked out Kanye and Kendrick Lamar as two artists making music which excites him.
