I think at some level, Kamen was thinking George Harrison watches horror films?!
I like that Kamen not only got hired to score Brazil, which is one of my favorite films and favorite scores, but he also became friends with Harrison, Cooper, Gilliam, and even singer-songwriter Kate Bush: Gilliam met her at Abbey Road, and introduced her and Kamen. Kamen and Nush were friends and colleagues for the rest of Kamen's life: he finished orchestrations for her album Aerial a month before he died in 2003.
