Ymke is the middle of the Verschueren sisters, who are better know as Sisters Only [who were featured on 24 February with the song Forever (till Eternity)].
Vive la Fête is Ymke‘s entry in the 2010 Junior Eurosong [the show that is used to select the Belgian entry to the Junior Eurovision Song Contest (JESC)]. Ymke gave a brilliant performance and won her heat but, unfortunately, did not the final. Ymke‘s sisters, Femke and Anke, can be seen towards the end of the video.
You can buy Vive la Fête on iTunes.
[Originally the video from Ymke’s Junior Eurosong performance was used here but the Belgian broadcaster has had all copies removed from YouTube. The video has been replaced by a video that contains the studio recording of the audio and a title card for the video.]
