Simon Cowell and co are treated to synchronised swimming group Aquabatique, yet more talented singers and a bloke pretending to be a Dalek with a pan on his head, among other things, on tonight's show (May 5).

The four judges have to decide on their final 45 acts this evening, cutting out the weakest links ahead of the tense live semi-finals.
But will any of this week's performers make the final cut? Hopefuls include singer Rachel Knowland, contortionist Lucky and an LED robot dance troupe called Area 51. It's the most diverse auditions show so far.
It's also worth waiting for Gatis Kandis, a comic who Simon Cowell brands "the funniest unfunny comedian I have ever heard in my life".
Britain's Got Talent airs tonight at 8.45pm on ITV1.
