I don't know which version you ended up getting, but the one transmitted on BBC One on Saturday suffered from a slight technical hitch. It was surrounded on either side by a rather dubious show about who can dance the best. The people performed on the show before Doctor Who which left time for people to vote shortly after which there was another show for the results.

For some reason the audio from the studio that the show was coming from was inadvertantly faded up during the bit with Rose in the basement with dummys. So during a moment of great suspense you hear a camp irish man saying 'So I go over there then?' and a few other choice TV phrases.

A few years ago there would've been people trained sufficiently enough not to let that happen. Nowadays they simply blame the equipment which is now bought off the shelf and is totally unfit for purpose.
