Sure, Zerbin's song has a slight hint of cheesiness that you need to get past, but then there is wonderful upbeat whistling that more than makes up for any bits you didn't like. There's nothing like a solid whistling section followed by an enthusiastic "hey! hey!" to make you smile, it works every time. See for yourself. And by all means watch the video.
