The album notes don't give the lyrics, but here are the notes for "Lynda":

LYNDA
This is a song of optimism and amazing courage.
Lynda is based on the mother of a Middlesbrough boy suffering from Spina Bifida. There are two ways we can rid this world of handicap. One is to destroy the handicap, the other is to destroy the handicapped.
The society that the many Lyndas of this world are fighting has opted for the latter.
I sang this song in the north of England recently and a young woman in tears said to me, ‘Don’t ever stop singing that song. I was expecting twins. They told me one of them was deformed… they took both of them…’

And as I said above, I think it's completely proper to express an opinion about abortion - but it's a travesty to legislate against this very personal opinion that must be made by the pregnant woman alone.
