Lyrics:

(Willcox)
I must
I must not
Homecraft
I must
I must not
Homecraft
I must be a bad cook
I must not bath
Homecraft
I must, I must
I must wear dirty clothing
I must be anti-social
Homecraft
I must
I must not
I must
I must not
I must not be quiet
I must answer back
Homecraft
I must, I must
I must be foul tempered
In company
Homecraft
I must, I must
I must bury the vacuum cleaner
Somewhere in the garden
Homecraft
I must, I must
I must remove the sheep notches
Off my husband's wellies
I must
I must not
