Easter Egg in Saint Nazaire

[WattersonPL]

Hello everyone! This is my first post on this site ^^

I found an easter egg today in vanilla Silent Hunter IV.
Not only there is a submarine base in Saint Nazaire, but you can hear an orchestra playing German Anthem near one of the houses in naval base, people are clapping and cheering and you can hear a deep ship's horn effect. That's it, but it surprised me ^^

Have a nice day!
