Hi.
There are several threads devoted to Harry Linn's songs c1865 to 1890 but they could do to be pulled together. We have dedicated threads to Harry Clifton and Joe Geoghegan with plenty of detail and dating, but there is very little on Harry Linn. Nothing much comes up by Googling also. Like Clifton's and Geoghegan's songs many survived in oral tradition.

Even if we only manage to accurately date some of them it will be useful. Even Kilgarriff only has a small list of his songs. Here are those we know survived in oral tradition:
Eggs for your Breakfast in the Morning
Get a little table
Jim the Carter Lad
When the Cock begins to crow
You never miss the water till the well runs dry.

(By the way I expressed an opinion on another thread that he may have written 'The Jolly Wagonner'. This was patently wrong as TJW dates back at least to the 1790s.)

Like many of his ilk (Clifton) he didn't live very long 1845-1890.
