Painting outdoors in the dark (?)

[Mara Schasteen]

I have a question that I am hoping someone might be abe to answer for me soon ... I've got a project painting a rock star during her outdoor performance on stage. I've got one hour to do it in, and it's going to be dark outside. Surely there is a solution to this seemingly impossible dilema?

Any and all ideas will be considered! Thanks for your help!
