Look for one singer and find three

After asking around I've managed to find three people from drama willing to be in my music video. Hannah has a tendency to die her hair every other day so i've decided not to use her incase i need to re-film something last minute and then her hair is suddenly blue! My girl-friend does drama and is also a musician, however a know that if i use her in my media i will end up not getting any work done. So i have decided to use my friend Ella for my media as she is a drama student and also does media, so she understands the workload and how to act around a video shoot also as she has ridiculously long ginger hair she should stand out as a performer.
