Super Furry Animals used signs to communicate with their fans.

The 'Demons' rockers - whose first language is Welsh - took to the stage at London's Somerset House on Saturday (18.07.09) and promptly triggered a rapturous response from the crowd with placards reading 'Applause' and 'Woah'.

The white posters appeared several times throughout the night - held as part of the venue's Summer Series of concerts - with fans giving the desired response every time they were brandished by frontman Gruff Rhys, despite them not needing much prompting to show their appreciation for a hit-filled set, which included early tracks such as 'Rings Around The World', 'God! Show Me Magic' and 'The Man Don't Give A F**k'.

However, the fans were dismayed to see posters bearing the words 'Thanks' and 'The End' signalling the end of the band's set, and some booed as it became apparent there would be no encore from the group.

Unlike previous Summer Series concerts held last week the crowd didn't have to battle with adverse weather conditions.

Torrential rain had hit the venue on several nights earlier in the week, hitting performances from The Ting Tings and Bat For Lashes, but failed to deter the fans from staying until the very end of their favourite act's sets.

Somerset House's Summer Series also saw performances from Lily Allen, The Enemy, Pendulum, The Mars Volta, Athlete, Calvin Harris and Grace Jones.
