OK, so automate it with a music function:

parallelStaffs = #(define-music-function (parser location firstStaff
secondStaff)
                      (ly:music? ly:music?)
#{ <<
     \context Staff = "StaffOne"  {
       \context Voice = "VoiceOne" {
         $firstStaff
       }
     }
     \context Staff = "StaffTwo" {
       \context Voice = "VoiceTwo" {
         $secondStaff
       }
     }
  >> 
#})

intro = \parallelStaffs
  {c''4 c''} 
  {c'4 c'}

verseOne = \parallelStaffs
  {d''4 d''}
  {d'4 d'}

chorus = \parallelStaffs
  {e''4 d'' }
  {e'4 e'}

verseTwo = \parallelStaffs
  {f''4 f''}
  {f'4 f'}

\score {
  {
    \intro
    \verseOne
    \chorus
    \verseTwo
  } 
}
