KPIG does a set of "dog songs" that includes the great "Feed Jake" by Pirates of the Misssissippi, the first hit country song I know of that mentions being gay in a positive light.
"If you get an ear pierced, some will call you gay.
But if you drive a pick-up, they'll say 'No, he must be straight.'
What we are and what we ain't,
What we can and what we cain't,
Does it really matter?"
