Go with what you know.
The bottom line of your post seems to indicate that there is no specific mention of a ban on clapping and dancing.
The bottom line of my post is that Scripture contains dozens of minute and highly detailed descriptions of Temple service and four descriptions of the Last Supper.
There is no outright ban on men being naked during the celebration of the Last Supper, but that does not mean that it's fine for us to strip down in the vestibule before Mass.
Surely you would agree that lack of a mention of a thing is not the same as a specific ban.
Again there are a million inappropriate things which are not specifically legislated against.
As far as "If you could cite the clapping and dancing taking place at the Last Supper, we could have a more directed discussion" is concerned, neither of us were there, so we really don't know what went on there except for what was reported to us. We got the overview, not the play by play.
The Gospel accounts reveal a great deal about the Last Supper - specifically that it followed the pattern of the Passover Seder as celebrated in Judaea of the 1st century.
The Mass as it exists today is traceable to two specific sources: the Jewish synagogue service and the Seder of Passover.
Each element of the Mass: the Introit, the Confiteor, the Kyrie, the Gloria, the Creed, the readings, the homily, the Offertory, the Canon, etc. can be directly traced to a predecessor in Jewish liturgy.
We possess extensive records and regulations concerning those liturgies from precisely Christ's time.
Nowhere do those liturgies contain dancing or clapping - which explains the complete absence of dancing or clapping from all Christian liturgy until the 1800s and from the Mass until 1970.
