The version of Napoleon's Farewell To Paris seems to be the same as the broadside versions. The Roud index lists 91 entries for the song (#1626). You can find a dozen or so copies at the Bodleian, here's a typical one: Napoleon's Farewell To Paris - Harding B11(2602).

Napoleon on the Isle of St Helena has 112 entries in the Roud index (#349) under a whole variety of titles (Bonaparte's Retreat/Boneparte at(on)(in) St Helena/Napoleon/Island of St Helena and more). Here's a broadside example at the Bodleian: Napoleon on the Isle of St Helena - Harding B19(130). (I haven't chased up all the titles there!).
