It's a rare event, and only happens maybe once or twice a year, maximum. But once in a blue moon a song will pop up on a national final that leaves both me an Mrs Apocalypse open-jawed and silent on the sofa. And it's never, ever happened via Portugal. Until tonight.But in the first semi of the FDC, a young lad who appeared to have crawled out of a skip crept onto the stage unassumingly and captivated the pair of us with his angelic voice and idiosyncratic delivery. Every other act on the bill tonight was a singer reciting some words. Young Salvador here was an artist interpreting a vision, and what a beautiful job he did of it, too.If they don't pick this lad to go to Kiev they want shooting. And if he doesn't even make it to the semi, I'm coming round to take all their first born after the next available flight. Seriously Portugal, this is your one golden hope from the last 20 years of trying. Do the sensible thing.
