Re: 'run To The Hills'
When I listen to the track itself, it sure sounds like "killing's a game." It sounds nothing like "their game" or "for game," and the latter doesn't even make sense grammatically. The line "killing the game" probably makes the most sense in context. I obviously need to dig up the old vinyl version I bought in junior high school and see what THOSE liner notes say. However, it is entirely possible that what Bruce sang on the recording is not what Harris originally wrote.
EDIT: Just did a quick check of all the live versions I own (Beast Over Hammersmith, LAD, Donington, Rock in Rio, Death on the Road, and even a bootleg of Donington in '07), and it is very, very clear that, irrespective of what Harris originally wrote or what the printed lyrics say, Bruce obviously thinks the line is "killing's a game." He sings it that way every time.
SECOND EDIT: Lyrics on Somewhere Back in Time compilation say "killings a game."
