Manang Biday chords

I have been looking everywhere for these chords, but haven't been able to find them.  Here is my "by ear" best guess for the first two stanzas:

Manang Biday (Ilocano folk song)

C                      G7
Manang Biday, ilukatmo man
G7                 C
Ta bentana ikalumbabam
       F            C 
Ta kitaem toy kinayawan
         G7               C
Ay matayakon no dinak kaasian

C                   G7
Siasinno nga aglabaslabas
G7                   C
Ditoy hardinko pagay-ayamak
F                C
Ammon ngarud nga balasangak
G7                       C
Sabong ni lirio, dipay nagukrad
