I say good for Arlene. Its a win win situation for her. I doubt many people who begrudge her the comeback after all the Arlene/Alesha cafuffle (is that a word?). I bet she's delighted and it can only serve as an ego boost for her. I for one am pleased for her....
If she was so inclined she could even ride triumphant onto the stage in her mobility scooter with a cup of tea and in her slippers! i'd pay to see that.
The McIntyre office have said that she was actually confirmed for the tour months ago. Kind of makes you think again about the wisdom of the BBC's decision to replace her.
