The Doctor(s) perform on Britain's Got Talent

'The Fourth, Seventh and Ninth Doctor's perform on Britain's Got Talent (or more like Gallifrey's Got Talent). What will the judges think of their acts?
Another comedy crossover, with clips from Fourth Doctor debut story "Robot", Seventh Doctor in "Greatest show in the Galaxy" and Ninth Doctor from "The Empty Child". Also Tenth Doctor cameo (sorry I couldn't find a more substantial role for him, though I thought of "The Shakespeare Code" and the Globe Theatre part).'
