What stands out to me in this interview is two-fold. First is the body language of the members, Alex Lifeson, Neil Peart, and Geddy Lee. There is no leaning away from anyone else. Each looks comfortable with his band mates and it's obvious that these three men are truly friends, not just band mates.
Second is drummer Neil Peart's chattiness. Anybody who is familiar with the band and Neil's books know that he is someone who sees himself as just another guy, but who is embarrassed by the adulation people show him because of his world-class drumming talent, not to mention his intellect that comes out in his lyrics and books. When he finishes a show, he immediately gets in his bus and leaves the venue. He values his downtime and his alone time and he usually lets his band mates do the meets and greets before shows. But in this interview, it's as if he's becoming more comfortable in front of the camera.
