I got "liturgical dancers" last Easter. I was out of town and picked the wrong church! I was not very happy.
Oh, yeah, the Altar Nymphs.
'Signing' is big locally. Not for the hearing impaired, but put to music (usually pre-recorded) as entertainment for all to enjoy. Liturgical dance was tried. And tried again. Luckily, it fell flat with locals, pun intended.
