Rocky Mountain Way

It seems like the story of a draft dodger who fled up into the mountains. The nonchalant way he says "Time to open fire" references the war that he was not a part of. "We don't need the ladies crying" is a reference to mothers who lost their sons at war, of which he was not one. "He's telling us this, he's telling us that" is a reference to Nixon lying all the time. I don't know who Casey is unless the line is actually "in case he's at bat" instead of "and Casey's at bat". "Time to change the batter" means getting a new president. The message of the song is that he would rather live up in the mountains than be at war or deal with the ridiculous political situation of 1973 (the year the song was written).
