Music Although I'm not the kind of Eurovision fan who knows the songs back to front before competition week but I do like to watch both semis which has been a frustrating experience in recent years because rather than show the whole of Eurovision's telepresentation, the BBC show has instead presented their own business with Scott Mills and whoever his co-presenter is (this year Mel Giedroyc) presumably designed to provide some background to the performers but I think draws away from the event itself.
Fortunately this year, the ceremonies were live streamed on YouTube and the sections not shown on the BBC snipped out and turned into their own videos. Here's the more prominent stuff worth seeing.
The Interval Act from the first semi final, a contemporary dance piece about the refugee crisis:
The Interval Act from the second semi final, in which humans dance synchronously with factory machines :
The Nerd Nation Part II (part one was in the first Semi but that's not on the channel for some reason)
And here are the whole live streams of both shows, should you want to enjoy the opening number for the second show again (which was the best Eurovision moment in years) and any numbers which didn't make it through to the final (and I'm sorry but San Marino was just depressing):
