If you've ever visited a bar frequented by Dutch people, you'll notice that the later it gets, the more likely it becomes that those present will break into drunken song, swaying and hollering strange, wistful-sounding lyrics. If you have no idea what I'm talking about, try visiting Cafe Nol on the Westerstraat. You'll get the idea very quickly. Or just visit their website - the music is right there waiting for you.

But what is the history behind this passionate hobby? The Amsterdam Historical Museum is currently hosting an exhibition called "Singing in Amsterdam" which details this, er, charming culture of song. It should help to provide insight into a uniquely Dutch and overwhelmingly Amsterdam-focused tradition.

Singing in Amsterdam is in the Amsterdam Historical Museum until 18 March 2007.
