How famous is Sam Smith? Not that famous, it turns out

I don't think I'm the only person who sees Sam Smith as a placeholder pop star - filling the space on bills; turning up; doing the job; but not an actual supernova pop star. You couldn't imagine a That'll Be The Day style movie being made about him; the biography isn't going to be a Hammer Of The Gods affair. More a Paintbrush Cheap From Homebase tale.

This impression doesn't go away with the discovery that people who had gone to see him at Red Rocks actually recognised him while he was mucking about before the show.

That's all a bit awkward, but at least we know the answer to the philosophical conundrum 'if Sam Smith is not on stage with a light shining on him, does he even exist?'
