Thanks Kitty! Perfect, and lots of new ones to me. This is not exactly folk (and I'm not sure that 'yearny' is even a word...) but a favourite all the same:

Got my bag, got my reservation
Spent each dime I could afford
Like a child in wild anticipation
Long to hear that "All aboard"

Seven, that's the time we leave, at seven
I'll be waitin' up for heaven
Countin' every mile of railroad track
That takes me back

Never thought my heart could be so yearny
Why did I decide to roam?
Gotta take that sentimental journey
Sentimental journey home
