First you should name the notes after a

variable = \context Voice = "voicename" \relative c' {
        notes here
}

After that.. the \lyricsto use "voicename" as a position mapper :)

Would it make a lot of difference to use the chord notation

<d bf>4 <bf f>2 <d bf>4 <bf f> <c f> 

with whatever ', octaviation required, (note that the octaviation considers 
only the first note of each chord), instead of:

<< { d4 bf c2 d4 bf c } \\
        { bf4 f f2 bf4 f f } >>

Try giving it a \context Voice = "name" first.. then send your comments and 
results .. so that it helps others looking for similar solutions.
