The lines in question (along with some of the Witch's "Lament") were cut from the original Broadway production in previews but Sondheim agreed to have the sections included on the OCR.
Stratford Festival's production also restores these segments leading me to guess that they can be obtained from MTI on request.
A verse from "Any Moment" is still missing.
The video of the Broadway production of WOODS is complete. So is SUNDAY IN THE PARK. SWEENEY TODD is complete as to what was on stage in the tour but the Tooth-pulling sequence and "Parlour Songs" were both dropped from the tour.
Cast albums are NOT "soundtracks."
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre!
I host a weekly one-hour radio program featuring cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com
