Last line of the second verse:
"But Love in the darkness takes a trust that's strong."
From the Live at the Cambridge Fold Festival disc.

I don't have the studio version of this, so I can't compare them.

In the first line "we have" is contracted to "we've".
Start of the second verse is "Blind sight", not "Hindsight". I had to listen to that one a lot of times to be convinced, but convinced I am.
"When" is missing from the third line of the second verse.
