Multiple stanza lines under second section of music

[Henry Law]

I am scoring a simple song which begins with its refrain, after which 
each stanza is sung, followed again by the refrain.  I therefore need 
the words of the refrain to appear once under the first few bars (on the 
line below the melody staff), but multiple lines of words to appear 
under the staff for the remaining bars.

Thus (warning: fixed-pitch font required)

Words of the refrain! Verse one.All together now .. :
                      Verse two, and we sing ..      :
                      Verse three, etc

I tried hacking it by creating a lyrics variable consisting of nothing 
but spaces and then prepending it within the \addlyrics command for all 
but the first verse, but (a) it's kludgy, and (b) it provoked a weird 
error where the chords of the second and subsequent systems were 
overlayed on the staff lines!

This must be a common thing to want to do: lots of folk songs have this 
layout. Can someone tell me the right way to do it?  (Small fragment 
attached, showing how I don't want to do it!)
