This pair of sisters gave bride Kate and her groom John a performance they'd never forget...
We love this! When Kate's two sisters - who were both bridesmaids at her wedding to John - stepped up to deliver their wedding speech, no one expected things to take a musical turn.
The moment they took to the stage, the girls asked the DJ to start the music, before they launched into their very own adaptations of some classic hits, adding in their own lyrics about the bride and groom.
Entwined with the likes of I Want You Back by the Jackson 5 and Everybody (Backstreet's Back) by the Backstreet Boys, the sisters relive the highlights Kate and John's relationship, including their first date.
The double-act finished their performance with a version of Oh Happy Days, with the audience giving the sisters a well-deserved standing ovation.
