Spoiler alert: everything is pretty much same as last year – you can have six people on the stage, you can bring a burning fake piano or a treadmill if you like, you can have as many pyrotechnics as your country can afford, and there’s a huge semi-circular digital projection screen too.
The Eurovision team have also kept the rule that was introduced for last year – performers have the option to pre-record their backing vocals rather than have live backing singers on stage, or they can have both. So we might hear a few more virtual choirs.
