Interesting. She still has her accent so I wouldn't have known that.
That was a brilliant song: "And we're all gonna shine a light together". That had winner written all over it. One of the truly last great songs at the competition.
The main issue in regard to the UK entry is the low reputation of Eurovision in terms of music credibility. No serious upcoming artist is going to touch it with a bargepole. Sam Ryder was the best by a long way in years. The only acts that predominantly enter it are karaoke level unknowns or those who have already had their success (Bonnie Tyler and Englebert Humperdink). Someone of the quality of an Ed Sheeran wouldn't have grown up thinking "must play Eurovision".
Music generally has got worse as there are far fewer big names. At festivals today all the big names from the past dominate, Elton John at Glastonbury last year where he was sensational. There is no Elton John equivalent today, or Queen, or Rolling Stones, or Pink Floyd etc. Similarly, Eurovision hasn't produced a good song in a long time (probably since that Katrina and the Waves one).
