"They say life is too short, the here and the now, and you're only given one shot
Could there be more, have I lived before, or could this be all that we've got"
Something about LaBrie's expression of the last words of those two lines and the theme of that first verse is very reminiscent of Roger Waters. I'm trying to figure out if there is some particular song I'm thinking of, or if it's more abstract than that, but it's probably something from The wall.
