"All You Need Is Love" (1967)
The Beatles recorded this Summer of Love anthem live on a worldwide television special broadcast by satellite. For the fade out, Martin composed what could be considered an orchestral proto-mashup, with fragments of "Greensleeves," Bach's Invention No. 8 in F Major and the big-band swing classic "In the Mood" all weaving in and out. But it was the last title that nearly got Martin in trouble for copyright infringement.
"EMI came to me and said, 'You put this in the arrangement, so now you've got to indemnify us against any action that might be taken.' I said, 'You must be joking. I got 15 pounds for doing that arrangement!' They saw the joke." The label thankfully didn't make Martin pay and compensated the "In the Mood" publishers.
