Yes it's firm, it is going to be Trijntje SOLO, with a song written by Anouk. Not exactly the revelation I was hoping for. Dotan would've been superb and gutsy.
While I admire her as a vocalist and for a long while I was hoping that she'd sing at ESC, I think she should've participated in the 00s when she was in her prime. Not now, not in the 10s. It seems a bit like a misfit, a regression.
It will all depend on the song.
