Viva is spanish not french the french verb to live is vivre. I think the song is simply about turning a corner in one's life. How when we were young there was a time when "we used to rule the world" so to speak. As age sets in and friends leave or go their own way those "streets" have all changed. A changing of the guard. I'm in my mid 30's now and have seen the streets I used to own completely changed. Theres new kings and such and that time period I remember has long since passed. The song really resonates with me and the nostalgia of a time long passed by. I know there are some religious undertones but I really don't think the song is Coldplay preaching to us about the loss of God and I highly doubt its about King Louis? Nope to me its just reminiscence of a time that has long gone by and being a spectator on the outside of it now. I do like rickrodz description though!
