  Bunches in the Tevatron are known to exhibit longitudinal oscillations which
persist indefinitely. These oscillations are colloquially called "dancing
bunches". Although the dancing bunches do not cause single bunch emittance
growth or beam loss at injection, it leads to bunch lengthening at collisions.
In operations, a longitudinal damper has been built which stops this dance and
damps out coupled bunch modes. Recent theoretical work predicts that the dance
can also be stopped by an appropriate change in the bunch distribution. This
paper shows the Tevatron experiments which support this theory.
