AceShowbiz - Paul McCartney has released a new animated video to accompany his 1993 protest song "Looking For Changes".
The hard-hitting promo tackles animal experiments in an effort to promote more reliable tests.
"Looking For Changes" was donated to PETA's campaign to end cruel experiments on animals, funded by the National Institutes of Health.
"I'm looking for changes that will continue the momentum of getting animals out of laboratories," says McCartney. "Experiments on animals are unethical, they're a colossal failure and a waste of time and money. We can and must do better."
The video is available on PETA.org.
