In 2006, on a now-defunct music community on LiveJournal, I found links to clips of "C'est les vacances" and "Dans ma fusée". I liked both songs, so I started looking for other songs by Ilona.
Here in Australia, if one wants any Ilona CDs, buying from an overseas site (such as Amazon.com) is pretty much the only option. This is the reason why I don't have any Ilona CDs.
I can afford a CD, but I don't have a credit card and therefore can't buy one online. iTunes Australia only has "C'est les vacances" which I've already downloaded.
