Hide a staff but keep it's lyrics?

[Marc Syvertsen]

Hello everyone, 
Does anyone know how to hide a staff but print the lyrics of that
voice?  Or something similar.  What I have is a melody, with lyrics, and
a bass accompaniment.  I can print those all out together, with the
chord names on top, over a staff with the melody, with the lyrics below
that, and a bass staff below that with the accompaniment.  But what I
want to print is a part for the euphonium player that has just the bass
part and the lyrics, without massive editing of the source file.  So is
there a way to print the lyrics of the melody staff without the staff
itself?  

Thanks!  I'm using 2.2.5.  My input file looks like this:


melody = \notes    \transpose c'' c'   \relative c'
{ 
        #(override-auto-beam-setting '(end * * * *) 1 4 'Staff)
        \override Staff.TimeSignature  #'style = #'numbered
        \time 2/4 
        \key f \major   
        \set tupletSpannerDuration = #(ly:make-moment 1 4)
        \times 2/3 { d8 d d  d d d  } |
        g4 f4 |
        \times 2/3 { e8 d e f( f) e} |
        d4 d |  \break
} 

text = \lyrics { 
        Hi -- nei  ma tov u -- ma na -- im she -- vet a -- chim gam ya -- chad
                
}

accompaniment = \chords   {
        d2:m g4:m d4:m c2  d2:m
} 

 chnames = \notes  \transpose c'' c' {    
{       
        %\set chordChanges = ##t 
        \accompaniment
} }

bassac = \notes { 
        \clef bass 
        \override Staff.TimeSignature  #'style = #'numbered
        \time 2/4
        \transpose c' c' {  \relative c' \key f \major d4 r4 g4 r4 | c4 r4 d4
r4 }
}



\score {
  <<
     \context ChordNames \chnames 
        
    \context Voice = one {   
         \notes { \clef bass }  
         \melody           }
    \lyricsto "one" \new Lyrics \text  % want these lyrics, preferably
under the next staff
        \new Staff { \set Staff.voltaOnThisStaff = ##t \bassac }  % want this
