Firstly, HAPPY NEW YEAR everyone!
Secondly, LEE I agree with you 100% - what a complete and utter let down. It was Ananova (normally quite reliable) who released the news that Paul and Helen would duet on Night Fever, and all the TV papers led us to believe that Helen would be on the first programme, and then be joined by Paul and Amma on the second one.
Yet another example of why not to believe anything written in the press, I think!!
