So here are the song choices
Saara Aalto
No More Tears (Enough is Enough)
Honey G
Stayin’ Alive
Emily Middlemas
Wishing on a Star
Sam Lavery
I Will Survive
Ryan Lawrie
Play That Funky Music
Matt Terry
Best of My Love
5 After Midnight
Boogie Wonderland
I was right with my prediction that Emily would do Rose Royce- but I would have gone with 'Love don't live here any more' 'Wish upon a star' seems a bit up beat 
Someone always does 'No more tears, and I always think 'but it's a DUET!!' - It's very Elfish though.
Ryan will be terrible, he really isn't funky, 5am will be karaoke, and I am already visualising a white shell suit for Honey G, like when Kenny Everett used to do piss take sketches of the Bee Gees. 
I think Sam will struggle. Any one who sings a song like 'I will survive' always loses
.
see y'all later.
