I found the online solver in seconds too so that will give the answer.
It looks fairly difficult to solve by hand at first glance because the 2nd most common letter in English doesn't turn up very often in it.
The double letters and the wordbreaks plus punctuation obviously make it easier to solve by hand though.
Last time I solved one of those was when I was a teenager when my brother didn't believe it was possible, took me a while (hours maybe), and the answer was
"Hey, hey, the clouds are away
There's straw for the donkeys
And the innocents can all sleep safely"
