THE X Factor finalists delivered a set full of high energy and greatest hits to a packed SECC.

Boy band JLS drove fans wild from the outset as they opened with Michael Jackson's The Way You Make Me Feel.

The first half of the show, presented by Jeff Brazier, drew some of the best performances from the TV series. They included stand-out numbers from Laura White with Fallin', and Ruth Lorenzo with Prince's Purple Rain. Barefoot Diana Vickers sung her heart out with Call Me and Take That's Patience.

A few cringe worthy acts came in the form of the Most Memorable Auditionees', but the second part of the show kicked off with Irish heart-throb Eoghan Quigg, while JLS performed Umbrella and Stand By Me/Beautiful Girl.

The true star of the night was 2008 TV winner Alexandra Burke, who showed her versatility by swapping from energetic Toxic to her Christmas No 1 ballad Hallelujah in a stunning set.

The finalists came together for the encore, chart topping Hero, before preparing for another SECC date tonight.
