A 44-year-old mum-of-two and a tool salesman are among the judges' favourite acts tonight, wowing them with Janis Joplin and Led Zeppelin covers.Amy Winehouse and Lady GaGa tribute act Nicola-Marie is more divisive and causes Gary Barlow to question "what planet" his co-stars are on.
Elsewhere, a hunky Scunthorpe lifeguard and an exuberant cover of Lady GaGa's 'Edge of Glory' cause a stir.
The X Factor airs tonight (September 1) on ITV1.
