Although I can't really take this man seriously, with his preposterous posing, constantly pained look, and supposedly "dramatic" performances, he sure releases some catchy tunes. This one positively bursts out of of the speakers with its 80-ish keyboard riff and addictingly hooky chorus. It is a shame that Amazon doesn't always give an accurate tracklisting of cd-singles, as there are often 2 or 3 different versions out there, and knowing which mixes are on a single is what makes me decide whether or not to buy it. The same here: it just says "Do You Know" twice. I'm sure there have to be some good club mixes of this song!
