In a rather special series finale Holly Willoughby is joined by the show's original host Cilla Black to give two sisters a surprise they will never forget. Back in 1999, Sue and Jacqui's mother appeared on Surprise Surprise, but she died six weeks later. Unfortunately, the only tape they had of the occasion went missing and Jacqui would love nothing more than for Sue to see it one more time. Tissues at the ready folks, it's going to be a blub-fest.
