Greig Stewart is a laser harpist who reached the Semi-Finals of Series 6 of Britain's Got Talent. He was twenty-seven at the time of his audition worked as a software developer and hailed from Glasgow.
His audition was shown in a montage of quick yeses alongside Lucky, Area 51 and Fish on Percussion. In his audition, he played the music to Tetris on a laser harp. David remarked 'You are the best laser harpist we've ever had on [BGT]', with Amanda adding 'It was a little bit nerdy'.
In the Semi-Finals, he again played his laser harp to a medley of songs including 'Cars' by Gary Numan, and 'Summer' by Calvin Harris, culminating his performance by being accompanied by backing dancers. His performance was buzzed by both Simon & Amanda. Alesha remarked 'I'm not sure [the Royal family] would get down to it', with Simon adding 'The beginning if I'm being honest with you actually sounded like someone treaded on a cat or something'.
