Quite right, lift and bounce not speed is the essence of a good dance tempo. When I used to play lead in a band I had a sytem of foot tapping that would bring the rest of the band, drummer included, back into line. If the dancers were walking, too slow, skipping just right, then lift the music with a bit of bounce in the tunes. My pet hate now is the trend of using a big drum in morris/street dancing which drags the tune down and the dancers plod around.
