shift lyrics closer to staff

[Marek Klein]

Hi,
in the example from the documentation,
how do I get lyrics closer to the staff?

(I tried it using the commented line, but it didn't work)

\include "gregorian.ly"
\score {
  <<
    \new VaticanaVoice = "cantus" {
      \[ c'\melisma c' \flexa a \]
      \[ a \flexa \deminutum g\melismaEnd \]
      f \divisioMinima
      \[ f\melisma \pes a c' c' \pes d'\melismaEnd \]
      c' \divisioMinima 
      \[ c'\melisma c' \flexa a \]
      \[ a \flexa \deminutum g\melismaEnd \] f \divisioMinima
    }
    \new Lyrics \lyricsto "cantus" {
 %\override LyricText #'Y-offset = #5
      San- ctus, San- ctus, San- ctus
    }
  >>
}
