This is musical theatre group, Barbershopera, who appeared on BBC Breakfast early this morning.
However, when the video for their song "I Could Have Married Kate" was played, one eagle-eyed viewer spotted something surprising.
Yep. The Beeb had accidentally broadcast a cock and balls that had been drawn on our future King's face. Tut tut.
You can watch the full video - cock, balls, n'all - here...
Update: The BBC has since apologised. A statement read, "The material was provided by Barbershopera but we failed to spot the offending material within it. We apologise for this."
