I just downloaded Sway by Dean Martin and I didn't hear him say the chorus, but Dean Martins voice does not sound like the voice on "Welcome to the Midwest". I just sort of breezed through the old song, but I do hear that is where the melody for the beat was inspired from (also, I might have got a short/different version).
I know Kaliko is talented, but looking at him with his big frame and hearing the chorus in the song, I can not picture him singing it. He could definitely pull it off, but look at a picture of him while listening to the song. I am more of an old school Tech fan and remember being up at 7th heaven getting Mitch Bade single and trying to find out when his Warner Bros album was gonna get released...as we all know that never happened. I am just not familiar with Kaliko as much as I haven't heard him much outside of any of Tech N9ne's albums. I've heard he has an opera bit at a show, so I can see him doing it, but it sounds like a sample. But whatever, I love that song and that chorus a lot.
