Yeah. No idea why it would be classified as blues, but it is. I've read a little bit about the music of that period and even have a couple CD collections. But the whole rhythm and blues thingie from the late 40s doesn't make sense to me, yet. That whole category of Black music between the big band era and ... the Motown era is one big smush, to me. If I had to categorize it, I'd call this song rhythm and blues, not blues. (Rhythm and Blues -- not today's R&B -- included a bunch of different genres, like gospel, country and blues.) Spo dee o dee (I looked up the spelling lol) sounds upbeat, to me. *shrug* Still would love to see the blues dance clips, though.
