"A LITTLE BOY WENT WALKING........."

My mother can't remember all the words to this song
This is what she does remember.........
" Alittle boy went walking, one lovely summers day
He saw a little rabbit, who quickly hopped away
He saw alittle river go winding in and out
And all the little fishy's were swimming all about

He saw a great church steeple........."

Can anyone help me? Thank, Lois
