Last night's episode of Britain's Got Talent featured none other than Simon Cowell's golden buzzer getting a blast for father-and-son singer-songwriters Jack & Tim.

The guitar-wielding duo bowled over the audiences and the judges with an original piece of music, all of which proved too much for Cowell who happily hit his golden buzzer - meaning the duo go straight through to the live shows in the next couple of weeks.

Each judge only gets one usage of it per season, and Cowell dropped his on this. Take a look and see why. Could we see them playing at another royal event in the near future?
