I LOVE this kind of lighting. We could rent a bunch of Kinoflo lights (the strips that people use like this) or improvise with other bits and bobs. The main thing is that they are narrow, restricted lights pointed back into the lens.
Freddie Mercury - he had a vocal range twice as wide as the average untrained person. And he never had any vocal training. By the way - the correct answer to "The Beatles or The Stones?" is "QUEEN!!!!!"
