First you need to go onto the special features part of the Calendar Girls DVD. You will see the making the movie, deleted scenes etc. and near the bottom of the screen, if you look closely you will see a small red flower, which doesn't blend in, but is hard to notice. If you go onto the flower, it will be highlighted and then press ENTER or PLAY (whichever one you use to get the film to play from the root menu). Once you've done that, there should be a page with lots of information about Lukemia Research and some scottish music playing.
