Adding staves (I think)

[Br. Athanasius Pelletier]

I am formatting "Peace Prayer of St. Francis".  

I am doing ok with verses one and two which share the same music but verses three and four each have different music and I am not sure how to make them work.

\version "2.13.35"

\include "english.ly"

\header {
  subtitle = "Peace Prayer of St. Francis"
  composer = "Sebastian Temple"
  % Remove default LilyPond tagline
  tagline = ##f
}

\paper {
  #(set-paper-size "letter")
}

global = {
  \key c \major
  \time 2/2
}

 c'' {
  \global
  \dynamicUp
  \repeat volta 2 {
  r4 e,4 e e e e f g e1 ( e2)
  r4 g,4 e' e e e e e f g d1 ( d2)
  r4 g,4 f' f f f f f g a f1 ( f2)
  r4 g,4 f' f f f e2 d }  
  %\repeat volta 2 
  \alternative  { {e1 ( e)} { e1 ( e2) } }
