There have been children using the Eurovision stage for test purposes last week. The aim was to let the children sing the 39 songs of this year.
So each song could be tested on stage in regards of light, sound and special effects. This might have been a great opportunity for the kids to stand on the newly build stage and to sing the Eurovision songs before the real singers come. But even more important is the fact that these performances have been filmed and recorded and send to the 39 delegations. With this precious film material the delegations can do the fine tuning for their entries.
