Who put grandma under the stairs

Heard a groan in the middle of the night
Grandma having an awful fright
Sitting there in my room
[?] I couldn't move

Try to warn her, try to save her
From the beast within myself
Try to save her, try to warn her
From the beast within my mind
My mind

Yeah, who put grandma under the stairs?
Oh no, it wasn't me
Who put grandma under the stairs
Oh no, it wasn't me

Try to warn her, try to save her
From the beast within my mind
Try to save her, try to warn her
From the beast within myself

[?]
To the cellar way down deep
There's grandma sitting there
Bound and gagged in a wooden chair

Try to save her, try to warn her
From the beast within myself
Try to save her, try to warn her
From the beast within my mind

Yeah, who put grandma under the stairs?
Oh no, it wasn't me
Who put grandma under the stairs
Oh no, it wasn't me

Try to save her, try to warn her
From the beast within my mind
Try to save her, try to warn her
From the beast within myself

Put the tourniquet around her heart [?]
Watch the back break [?] watch the [?]
A loving kiss on her lips
Darling grandma I [?]

Try to save her, try to warn her
From the beast within my mind
Try to save her, try to warn her
From the beast within myself
Myself
