To be fair I think the only group, at this moment, in time that could pull off the current Euro-pop style music, for the UK, is Steps
Why does it need to be a 'euro-pop' style song? That's where the UK's gone wrong before and when was the last time a 'euro-pop' song won or did well at Eurovision?
Because you are thinking of 80's Euro-pop followed by Black Box style Europop, more than likely!
Current Euro-pop trend wdid actually win the contest this year!!!
ALL UK winners have had Euro-pop style songs for their particular era. Like any style of music it does evolve.
If anything Steps would be perfect entry for years contest, and we don't need any "song For Europe" competition - just let the normal Steps songwriters write it as a normal song, and nothing special!
Also, I believe that there should be no inter-country publicity of each other songs, until after the event. Then the "phone voters" can decide on the night rather than knowing what to song to choose weeks/months before.
