Boys
Che - 'Writing's on the Wall' (Spectre, Sam Smith) - let's be real this is 98% going to happen isn't it
Mason - i have no bloody idea

Girls
Lauren - she'll get something safe like 'Wind Beneath My Wings' and grannies will cry
Louisa - idk, Son of a Preacher Man?
Monica - I just want to throw her under the bus, so just have her do 'Lose Yourself' and start vomiting spaghetti all over the stage.

Groups
Reggie n Bollie - Bad Boys obviously - although if they just throw 'Under the Sea' at them then that's fine too
4th Impact - I assume they'll do that Burlesque song they flopped with at 6 Chairs but hopefully they don't. Or Lady Marmalade. Instead I demand they reenact the entire Spice World movie from start to finish.

Overs
Anton - If 4th Impact don't do the entire Spice World movie then he can. Or 'Can You Feel the Love Tonight?' or s/t to win back the voters Or Across 110th Street.
Max - idk he'll probably do something like 'Everybody's Talkin'' from Forrest Gump won't he
