GENEVA (AP) — With an assist from Paul McCartney the Paralympic Games starts its 100-day race on Monday to the opening ceremony in Paris in August.

The former Beatle has let “We All Stand Together” — the signature tune from an award-winning animated film he wrote and produced 40 years ago — be used in a promotional film for the International Paralympic Committee.

“Sir Paul really understands what we stand for as a movement and he was so generous to us,” IPC president Andrew Parsons told The Associated Press. “He was not difficult to convince, it was something that came very naturally.”

In 100 days from Monday, the Summer Paralympics opening ceremony on Aug. 28 will play out along a section of the Champs-Élysées and Place de la Concorde. The 4,400 athletes taking part will compete over the following 11 days watched by up to 2.7 million spectators in venues including ones beneath the Eiffel Tower and at Versailles Palace.
