Lyrics used on the Compleat Dancing Master are something like:

I'll have a dance with a dusty miller
Jolly with his new coat on
I'll have a dance with a dusty miller
Jolly with his new coat on

Down the middle, down the middle
Play your fiddle, pretty little dear
Up the middle, hey diddle diddle
[undeciphered bit], pretty little dear

If you're young and wish to marry
Who'll you choose to be your wife
If you marry John Brown's sister
She will plague you all your life

Don't you tease her, try to please her
For she is my pretty little dear
Don't you tease her, try to please her
For she is my pretty little dear
