It's the sixth week of the audition show, and so far there has been some pretty impressive acts seen by the judges (including the epic moves of Cavan lad Dylan Byrd) and even a few gold buttons pushed... although many more red buttons. The search continues tonight for judges Simon Cowell, David Walliams, Amanda Holden and Alesha Dixon as they hope to find the act that will follow in the footsteps of previous winners Collabro, Diversity and of course, Pudsey the Dog.
