I mean- come on, that's just an excuse to trot out more sappy ballady shit. where are the proper themes? Bring on Abba week, Death metal week, bugger it- even Cliff Richard week if it means they will sing something that actaully follows a theme .(A spoiler claims Johnny is singing the Jason and Kylie classic 'Especially for you' wtf?!)
Mind you, in light of poor wee Janet losing her grandad this week, it could be quite emotional 
Will keep eye out for list of songs....
