Question of the week – 13 September 2017

I was a bit disappointed that nobody got the correct answer to this question at the Quiz at the Green Linnet on Wednesday:

After a performance of almost 20 years,
who is going to bow out in a fiery Grand Finale on Friday?

Après presque 20 ans de performance,
qui va tirer sa révérence dans un Grand Final embrasé ce vendredi?

Is the wording too cryptic?
