This, maybe?

\version "2.6.3"

upper = \transpose c c' { \time 3/4  c4 e g | c e g | c e g }
lower = \transpose c c { \time 3/4  c2. | c | c }

verseOne = \lyricmode { One two three | four and six | seven }
verseTwo = \lyricmode { Eight nine ten | e -- le -- ven | twelve }

\score {

  \context StaffGroup <<
    \context Staff = upper <<
      \upper

      \context Voice = lyricsRhythm {
        \time 3/4
        \relative c'' {
          \hideNotes
          c4 c c | c4. c8 c4 | c2. |
        }
      }
      \lyricsto lyricsRhythm \new Lyrics \verseOne
      \lyricsto lyricsRhythm \new Lyrics \verseTwo
    >>

    \context Staff = lower \lower
  >>

  \layout { }
}

Note: I had to add 
  \relative c'' { ... }
to avoid warnings ("ignoring too many clashing note columns").


Best,
