Roberto,

It sounds to me that the missing lines may be:

Then up spake a witch woman clear and loud
Who had been hiding alone


Your transcription sounds fine to me. The only places I hear differently are:

Stanza 8: For your love he has RUN

'Slumber' sounds plural to me wherever occurring - 'Slumbers'

13: Three times she's danced ROUND the soles of his shoes

14: Saying, love, BY this token

17/1: no 'and': ... feet, master, made my reins ring

19/1: no 'and': ... wings, master, made my bell ring

21/3: That if YOU'D LIE still when a-bed at night

23/3: ... your LOVE OF so long

Hope the above is of some help.
