At what time does the band soundcheck?

[Zsa Zsa Gabor, what's my life for ?]

I work 1 min. walking from the HMH in Amsterdam so I figured I might go and have a look. What time do the soundcheck? Anyone? Or rather when does Moz arrive

 

[Houdini]

He arrived at 5 o'clock at one of the Scandinavian shows, I heard.
