Ok, well, these people are from the amazing cast(s) of the Cats UK Tour of 2006-2008, who between them went to Italy and Portugal and Germany during the tour and were just generally wonderful and fabulous. I think I sort of went with a theme of Victoria (played by the amazing Rachel Ensor) dreaming of the show in this particular video, but really it's just a tribute to some of the most amazing people I've seen in this show ever, because they basically danced up a storm.
p.s. I love this album so much and would definitely recommend it to anyone!! Buy it, you know you want to! hehe
