Hesk-

Yes, adding "Now" to the last line permits us to keep the rest of that line with a number of traditional nautical settings such as "Liverpool Judies/Row Bullies Row":

Here comes the Old Man looped to the gills,
His hands in his pockets and a mouth full of pills;
He's cussin' an' hollerin' from dawn to the dusk,
"Now get a move on, you ham-handed louts!"

Cheerily,
Charley Noble
