Hahaha, well a lot of contestants are around the same age as me, so whenever I watch an old performance I'm like: 'they're so old now!' and then I realize that the same goes for me :P
FYI: All 'now' videos from Belgium are from a show that was broadcast on 31/12/2017 called '20 jaar Ketnet'. It was made to celebrate the 20th anniversary of the children's TV channel Ketnet. There were multiple segments, one of them having the JESC contestants.
Rachel Traets should represent Netherlands in Eurovision 2020. She placed 2nd in 2011, maybe it could be better if Netherlands will win in 2020 just like Poland did this year.
Interesting you showed a lot of Georgian numbers. What's your guess most of them redid their songs just before JESC 2017? It was like a reunion of all of them?
Yes! Georgian TV made an episode where they invited all former participants and they talked about JESC and stuff (I don't speak Georgian, so actually I have no idea :P)
I reckon the Bee kids were a bit embarrassed to go and sing in their imaginary language again but it's cool that JESC in Georgia was so popular like how popular Eurovision in Portugal was!
