Do you hold that dancing, clapping, etc. are forbidden on Shabbat and Yom Tov as per Beitzah 30a?
Dancing, clapping (in the usual manner), etc. are asur on Shabbat and Yom Tov - see Rambam's MT Shabbat 23:5. It should be noted that people holding hands and walking/shuffling around in a circle is not dancing and is mutar, as was once pointed out by haGaon haRav Moshe Feinstein z'l. Clapping one hand on the back of the other is mutar. The Talmud (Beitzah 30a and Shabbat 148b) states that people do so anyway and one need not chastise them; better that they do so unwittingly.
