For what it's worth, I kind of agree with the opinion that "Castle" is truly folk music in its purest form. But that's not to say its not okay to not be as fond of it as some of the other, shall we say, more "upbeat" things that Gord has done. It kind of depends what you find appealing. For some who really like "Canadian Railroad Trilogy" which I feel is ALSO a pure form of folk, these same people find feel that "Castle" lacks the vividness and color of "CRT". I guess it's kind of like comparing apples and oranges. Both songs are excellent, but everyone is going to have different preferences.
Just a little note of interest (and then again, maybe not, but being a mother, well....

) My son recited the entire song "The Ballad of Yarmouth Castle" as a poem and all from memory for a third grade language fair and won first place for his efforts. Just had to tell you guys that. But then, of course, I'm not biased or anything ....
Stay loose, eh?

"Love and maple syrup
go together like the
sticky winds of winter
when they meet....
If you go into the forest
Gaze up through the trees
The sky is white.
You can understand
What makes the forest
Greet the man
Like a mother's only
child ..."
