Ode to Einstein

Hey! So I was looking into creating a sound collage more or less. I am still trying to figure out the details, but it will never be just my voice speaking the poem as the main chunk of it is now. I just wanted to give an idea of where I am going with this. I was wondering about using clips from movies etc and how that worked in terms of copy right. Not entirely sure if I want to stick with this or not. I think it could be really interesting but at the same time, might be too much. My Plan B is an interview that I have coming up this week.
