Paul McCartney

Paul McCartney has revealed where he finds inspiration to finish writing some of his songs — in the toilet.

The former Beatle, 72, disclosed how he goes about songwriting — and why he avoids penning tracks about sex — in an interview with Q magazine.

And he also hinted that his US wife Nancy Shevell was left impressed by his latest collaboration with rapper Kanye West, because of the song’s use of “the n-word”.
