Fleur could pretty much do a medley and soar through
I would pick 'How Will I Know' for her though.
Andrea - One Moment in Time (hasn't he nailed this already?)
Ben - probably 'Saturday Night's Alright (For Fighting)' or 'Something About the Way You Look Tonight'
Only the Young - I can see Louis forcing 'Crocodile Rock' on them
Stereo Kicks - either something overly romantic like Your Song, or woefully miscast like Don't Let the Sun Go Down on Me
Stevi - I demand 'I'm Still Standing' after tonight's result
Lauren - actually she'll probably do the Ellie version of Your Song, the dreary cow
