Song is between 2,5 and 4 minutes depending on the version i'll choose, i'd say get as many clips as possible. the second matter is how many "girls" are in the video maybe we'll get sickone's daisy to be in as well and some other's diversity would be neat, otherwise you have to film more
[EDIT] don't forget your female skaters have to be "tall and tan and young and lovely" ...
