Mutya Keisha Siobhan played their first show together for 12 years when they took to the stage at London's Scala on Thursday (August 1).

Performing Sugababes' classics as well as lesser known tracks from their 2000 'One Touch' album, the trio were positively beaming in front of a packed appreciative crowd.

The Scala concert sold out in 14 minutes according to a press release issued by Edge Publicity on July 12.

Tracks such as 'Stronger', 'No Regrets', 'Push The Button' blended in harmoniously with new songs such as 'Flatline', and 'Love Me Hard', a track written by Spice Girls' songwriter, Biffco.

The biggest cheer of the night came when Siobhan Donaghy successfully took on the vocal challenge of singing Heidi Range's part in 'Stronger'. Range replaced Donaghy in Sugababes.

Mutya Keisha Siobhan have been working with Dev Hynes, producer to Solange Knowles, and legendary songwriter, Diane Warren, known for her power ballads.

The last song of the night was 'Flatline' with a final refrain of 'Push The Button' (see videos below).
