Opening of Grand Final - Eurovision 2015 (First dress rehearsal) 

It's so cool they let everyone watch the dress rehearsal ;)

9:34 it's playback

9:13 Hey, did you ever seen this? Look closer to the choir. While the rapper performance, you see the kids cheering and waving the flag, in the final live, there are many flags of each countries had to participated. However, during rehearsal, only two flags are there, Austria and Australia. Did you know how explain that the two different flag waving by the choirs? Here is the truth, Austria, which was the host country in that year at Vienna, and Australia, as a latest debut in the contest - that was the solve one!

its cool to hear the click track start up 4:00 mark and at the 5:10 mark right as the stadium goes dark it stops, thats cool!
