UPDATE (21:33 local time): The EBU went on to offer SuRie a second chance to perform her entry onstage, however SuRie has refused and will therefore not perform again tonight.
Last year's victor of the Eurovision song contest in El Salvador Gathered displeased that after his triumph of the qualitative component of the performances has changed for the better.
The performance was going well on the night... that was before a stage intruder interrupted the performance mid-song, shouting a now unclear message into the microphone which was snatched from the British representative.
Viewers praised SuRie for her handling of the rattling moment, as security bounded on stage and dragged the man away.
But SuRie believes her mix of music and "high-end technology" will make her stand out in a crowded field of competitors.
"YouTube decided that I must like the song of the Israelites".
"It creates a really strong atmosphere on stage, letting the music - the melody and the lyrics - do their thing". But she's also been buoyed up by how well her song has gone down with most of the Eurovision supporters in Lisbon singing along when she performs it.
Coming after last year's much-seen stage invasion, the question has to be asked: How does this keep happening?
Russian Federation made a shock exit from the competition during Thursday's semi-final - the first time the country has failed to qualify for the final since the current system was introduced.
Ireland - which holds the record for most Eurovision wins (seven) - is back in the final for the first time since 2013.
"I think it transforms the city because you have peope from all over the world just being happy".
Wearing the same short purple dress she wore in the semi-final, Mauboy was the 16th performer out of a total 26 countries competing, with some of the hot favourites, Cyprus, Israel and Ireland still to perform. I opened it, but it was a bad song.
As well as the TV cast, you can also listen in via BBC Radio 2 with Ken Bruce from 8PM as well.
