When she announced what song she was going to sing, one of the panel was heard to remark "Big song". The thing that amazed me with the performance was within three lines of lyrics she had the whole audience on their feet applauding like mad. Don't quite know how you'd stage manage that. At forty seconds into the pre-performance interview with Ant & Dec the lady said that she was going to "rock" the audience - she certainly did that. She thought she had the audience after the first verse, she knew it as she paused in the small instrumental interlude before the last verse and then she really let them have it, as beautiful and perfect as watching a Spitfire perform a "victory" roll. The very best of luck and good fortune to her - absolutely magnificent!
