lyrics following split voices

[Paul Scott]

Hi,

When I use << { } \\ { } >> without voice naming to show note variations
in different verses of a song the parallel music gets skipped by the
lyrics.  I have read all the relevant 2.11 docs without finding a way to
name the voices so that the lyrics get attached to the parallel music.

Any ideas or pointers to documentation to make more sense of this?

TIA,

Paul Scott
