"Dancing" before the Lord

[Anna]

Clearly the Bible speaks of Dancing before the Lord, as David did, however, what type of dancing is appropriate in a worship service should be the question.

The link below is to a video taken of a Church Anniversary celebration in the Church's sanctuary.
I would like to have comments from any and all, regarding the appropriateness of this type of dancing in a sanctuary:
