Third Voice?

[Chris Crossen]

I am engraving the Hallelujah Chorus from Handel's Messiah. There is one
measure (87) where I think I need a third voice in the treble clef. I have
attached an image of measure 87. The red-underlined notes in the image are
what is missing when I render my Lilypond. A cut down version of my source
for just measure 87 is below.

I believe I need a third voice for the missing 8th and 16th notes, but I
don't know how to structure it. My Lilypond is using a template from
Frescobaldi.

Can someone show me how to add the third voice?

Thanks,
Chris Crossen
