With the painful knowledge that Mel Giedroyc and Sue Perkins will be leaving The Great British Bake Off when it moves to Channel 4 from BBC One, fans were feeling particularly emotional watching the latest episode.

The duo sang a little ditty as they introduced us to the Bake Off’s first ever batter week and it sent tearful viewers into a tailspin.
