"Ceilidh dancing is not meant to be watched. You can wear whatever you like... As a spectator sport it's extemely dull, though for the participant it can be so exhilarating it ought to be illegal."*
Drinking is allowed and experience optional.
The caller's job is to walk everyone through each dance and keep them going once the music is added.
* Andrew King, Moondance Ceilidh band
