After Montenegro did their first rehearsal on stage, Iceland started to sing, with Greta and Jonsi. We can see at the back mountains moving and a winter-type scene, perfect for the song and country they represent. Greta will be – as in the preview video – with the violin, joined with Jonsi singing with her and four backing singers helping them. Greta will have the same dress in the semifinal, but Jonsi will have a type of smoking.
