I would say Saara singing No More Tears by Donna Summer in disco week.

And her backing dancers throughout were awesome nearly every week.

What was your favourite song performane of the whole series ?

Probably Saara's "Diamonds Are Forever" routine. Pure cheese, but so good
Although her week five sing off is where she truly won me over. Went from strength to strength off the back of that.

The only performance I've liked outside of Saara's is Emily's "Creep".

Probably Madness.

But Saara's Bjork song was a good second.

Relly - Shackles
Matt - you don't own me

I have a soft spot for Sam's Hello.

Emily singing creep

Saara The Winner Takes it All or Emily Creep.
