From no lyrics to 4 verses

[Keith Dunsire]

I have a hymn that I wish to reproduce with all verses under the melody and 
guitar chords above. The problem is that the hymn starts with an introduction, 
so no lyrics there, only guitar chords. Then there is the chorus which has one 
lyric line, melody and guitar chords, Finaly the four verses themselves. 

Can anybody tell me how to construct the \score to achieve the layout described 
above. that is, introduction (no lyrics), chorus (one lyric line), and then 
verses (4 lyric lines).

Thanks
