Here's what Jessie had to say about this scene when it was first released in 2014:

"Cherry and I take turns to pie each other while singing "3 whipped cream pies on the wall". We first do it in nice black evening dresses, one singing and the other miming instruments, violin, piano and cello. Then we do the same but in bikinis.

No, I am not going to enter a singing competition anytime soon, but hell, it was fucking funny to film! It was a custom scene and Cherry and I had to practise several times as we kept getting the words wrong or forgetting something. I forgot how a cello works and never did quite get that technique down. But it's funny and we both get pied so all is good with me!"
