This was recorded live with an orchestra. McCartney allowed guitarist Henry McCullough to improvise his solo in the final take. McCartney recalled to Mojo magazine October 2010: "I'd sort of written the solo, as I often did with our solos. And Henry walked up to me before the take and just sort of said (adopts Celtic brogue), Hey, would it be all right if I try something else?' And I said, (uncertainly) 'Er…yeah.' It was like, 'Do I believe in this guy?' And he played the solo on 'My Love,' which came right out of the blue."
As for McCullough, it was a career-defining moment for the young guitarist, as overruling Paul McCartney is rarely prudent in the studio. In our interview with Henry McCullough, he explained: "I can't remember what it was I was asked to play, but whatever it was I refused and said that I was going to change the solo. So Paul says, 'Well, what are you going to play?' I said, 'I don't know.' Well, that put the fear of God in him, I think. Because there I am, just me and a 50-piece orchestra in the studio and there's George Martin in the control room and Paul. I knew it was going to be a turning point in some shape or form regardless of what I came up with. I don't use pedals or anything, so I just plugged into the amp and that was it - it was all over and done with very quickly. I went in and they ran the track and I did it once and went back into the control room and there was silence. And I thought I was going to have to do it again or something. But it was not the case.
This was a turning point for me, because I was able to, in later life, look back on it and say, 'That's what I did for Paul McCartney. I gave him that solo.' But it came from somewhere else and through me to Paul, and this is what flabbergasted him. And not having worked like that before, it was a little new to him. I came out of the studio that day and I was a very happy man, because I had confronted this thing I knew was there, that hadn't quite shown its head. And that was where I left me mark, you know."
