Peter Lambert is a variety act and circus performer who reached the Semi-Finals of Series 9 of Britain's Got Talent. He was aged thirty two and mainly performed at holiday parks as an entertainer at the time of his audition.
In his audition, he boarded his unicycle and began to spin several plates atop of sticks on his smaller stage, rode a makeshift see-saw made up of a piece of metal and a metal tube, and juggled several sharp objects, catching each sharp objects handle, and collecting each of the spinning plates. David remarked 'I've never seen anything like it [and] all of those things all at once is very very impressive', with Alesha adding 'Your a bit nuts, but I love that about you'.
In the Semi-Finals, he rode his unicycle around flames, before dismounting from it, a woman chopped an item on a table with an axe, before Peter noticed a ladder, and climbed it making it wobble a crash mat in front of the fire, before women passed him axes as he remained atop of the ladder, and juggled them before throwing them all down onto the crash mat. Amanda remarked 'You kind of remind me a little bit of Stephen Mulhern', with Simon adding 'You are a trier, and your enthusiasm is very infectious'.
