I found the song
I was looking for the other day. It's called "Let It Roll," and it is one of the catchiest songs ever -- Big Band swing meets Southern rock. I just didn't know it was Little Feat who did it until I finally googled it last week.
And now that the song is safely stored in my MP3 player, I can listen to it as much as I want to. Heh... in fact, when I do listen to it, I have to replay it at least three-four times. It makes me want to jump up and dance madly around the floor every time I hear it (which can be a bit awkward when I'm in the grocery store at the time.... *g* ).
