It's only a guess, but he may be referring to the tune in the "long dance" section of O'Neill's which goes by that name. In which case, yes, it's basically the same one, though O'Neill's version varies a bit, especially in the third part. But it's recognisably the same tune.

Grooveshark's nifty, SC - thanks for turning me on to it.

PS: Being Napoleon's harpist was the least of Bochsa's adventures: he later had to flee France, having been sentenced to imprisonment and branding for committing forgery. He went to England, became the first harp professor at the Royal Academy, got into more trouble for fraud, ran off with the wife of the guy who wrote Home Sweet Home and ended up dying in Australia. (His paramour's husband only outlived him by three months, leaving her free to marry a New York diamond merchant.)
