I am a big fan of Tintin & Milou by Hergé since my childhood.
In german Tim & Struppi. In September 2015 there was an open air event at Chateau de la Hulpe, a beautiful castle just 20 min south of Brussels.
An opera-style performance of Les bijoux de la Castafiore.
Die Juwelen der Sängerin.
I was lucky to get a ticket.
It was pretty cold that evening, and sadly, as far as I know, the Opera has never been performed again, although a tour in france had been planned, but it was really a great evening.

If you see them on stage, you know them all, if you are a fan!
I didn’t find much other footage of this opera, only some from TV:
German
Italian
French(Belgium):
