The Missing People Choir have been tipped for success on Britain's Got Talent 2017.
BGT kicks off this Saturday night and one act is already been touted as a possible winner.
The Missing People Choir performed original song I Miss You for the BGT judges at auditions earlier this year.
The group of singers is made up of relatives of missing persons across the world.
Simon said: "We’ve had a lot of people coming on to highlight different causes this year. We had something this year called the Missing People Choir, which was very emotional.
"They’ve got a shot at winning, I think. I remember on the day thinking that it was special."
Speaking about so-called sob stories from contestants, Simon went on: "What’s quite interesting this year though is a lot of the stories I heard, they didn’t come on and shout about it, it was me asking questions and finding out about the story.
"Some of the stories we heard were really quite incredible, they were about real things that have happened in their lives and I think they were sincere. They weren’t necessarily sob stories, they were human interest and for me, that makes it more interesting."
As well as The Missing People Choir, children acts have also impressed this year.
Simon revealed: The kids have been great. Do you remember Connie Talbot in series one? She sang Somewhere Over The Rainbow, I remember that moment, along with Paul Potts, vividly.
"There’s one little comedian who is so funny, so cheeky, so naughty, but I think people are really going to like him. I thought he was hilarious and comedians don’t make me laugh very much."
Britain's Got Talent 2017 starts Saturday, April 15 on ITV from 8PM.
