Chord changes under voltas?

[eric raeburn]

There was a short thread on this topic in Feb-March 2003 ("Chords under 
voltas?"), apparently unresolved, and I could find no more recent 
discussion of this topic.

I am using Lilypond to produce jazz leadsheets.  Lilypond prints chord 
symbols above volta lines.  This is most unorthodox and 
disconcerting--the symbols should be above the staff but below the 
volta.  I am using 2.10.29.

Is there a workaround, or should this be reported as a bug?

Thanks,
-Eric
