Another version

She wears her silk pyjamas in the summer when it's hot,
she wears her flannel nightie in the winter when it's not.
And sometimes in the springtime and sometimes in the fall
she jumps right in between the sheets with nothing on at all.

Chorus:
Glory, how I'd like to be there,
glory, how I'd like to be there,
glory, how I'd like to be there
in the springtime and the fall!
