wordwrap

I have a text file that is pretty long. Any easy way to "undo" a M-q (fill-paragraph) on a file that was written and saved a while ago?

For example, I want to change this:

They're coming to take me away, ha-haaa!!
They're coming to take me away, ho-ho, hee-hee, ha-haaa

To this:

They're coming to take me away, ha-haaa!! They're coming to take me away, ho-ho, hee-hee, ha-haaa
