What about lighting?
In general, Wraggle Taggle rely on venues to provide suitable lighting. It is best to dim the lights in the hall where the ceilidh is taking place, as this can encourage people to dance. We would advise against making it very dark as you do need to see what you are doing!
It is also desirable to light the band so they can be seen, especially the caller if you book one. The controls for any stage lights are often locked unless someone specifically organises access. Wraggle Taggle do bring one spotlight, a pinspot and colour wheel and a light sequencer just in case there is no lighting at all.
