Lyrics and Chord Names with no notes

[Richard Shann]

I can't seem to find a snippet for typesetting lyrics with chord symbols
above with no staff visible between them. (The invisible staff would
give the spacing, that is rhythm).
Below is the nearest I have got - the only problem is that the
transparent staff takes up space (even if you reduce the number of staff
lines).
Is there a known method of getting lyrics with chord symbols?
