I can't remember a song that started with a better hook. The "pow" about 12 seconds in is completely irresistable. The Moodys had some terrific intros: Ride My See Saw and You and Me are strong contenders.
If they had stayed together in the 1970s, I think they could have been a stadium band; they had a terrific catalog and when they reformed around 1978 they still could bring it. They just missed their wave, but at the top, they were as good as any band has ever been.
