Okay, a brief search on Google turns up the fact that "My Girl's a Yorkshire Girl" was a short movie in 1909, being basically a music video (and we thought those were something new!).

Both of these song titles are on the CD "Dancing in the Street" by Kevin Grunill (click here), although apparently he just plays the mighty Wurlitzer and there's no singing involved.

It's also called a "regimental" piece, and apparently was played by the 1st Bn Duke of Wellington Regiment as part of their marching music (click.)

It was sung by Charles W. Whittle, an early music hall star, in Yorkshire.

It's mentioned in Joyce's Ulysses.

But I'll be darned if I can find the lyrics. Sorry!
