The act I am trying to remember was from the first few years of BGT (I think), this act was a guy, on his own, on the live shows dancing with a broom...I am sure this happened. It wasn't the one with the Michael Jackson act, I have vague memories of him in a blue suit. Can anybody help?

Jack Reeve from series 1? His semi final performance doesn't seem to be on YouTube though.

There was a broom dancer called Oliver Moroney, but that was just two years ago and I don't think he got to the semi finals

my guess could be George Sampson probably not right though?

Not Signature, who had a sidekick with a broom? They were on BGMT again last night.
