In a press release the Skype team said: “Paul genuinely loves Skype and, inspired by our existing Mojis, was excited to lend his voice to the Mojis family. Likewise, we were over the moon to work with Paul, and it was a great creative challenge for us to create the animations to compliment his legendary sound.
“We are thrilled to lend some of his magic to a set of Mojis conveying the world’s most powerful emotion, love, through music and art. If you need a creative way to share your feelings, let Paul be your cupid. Not a bad way to serenade the ones you love, right?”
Personally we love hearing McCartney saying “Mojis”.
