Well, the group seems to be named "the Miserable Offenders" and the information about the CD is here. There's some information about the duo and an address for a distributor here.
The song is listed at an Anglican Hymnal website, but the link doesn't work, so maybe you could find it in a print version somewhere.
Woohoo! Found it here. along with several others. Lyrics in a moment...
I'm stealing their HTML, so I hope this works:

WHAT IS THE CRYING AT JORDAN?

What is the crying at Jordan?
Who hears, O God, the prophecy?
Dark is the season, dark
Our hearts and shut to mystery.
Who then shall stir in this darkness
Prepare for joy in the winter night?
Mortal in darkness we
Lie down, blind-hearted, seeing no light.
God give us grace to awake us!
To see the branch that begins to bloom
In great humility
Is hid all heaven in a little room
Now comes the day of our healing
In joy and trembling a Word is giv'n!
Our God is born into our lives,
Oh, let salvation dawn!

(1982 Hymnal #69)
