Meggy13 We have done a few EYB's and have always received the provisional rehearsal days and times in the audition pack. The dates are always the same, it's just sometimes slightly different on times and the rehearsal venue may not be confrmed. It is usually a secondary school in the area that has plenty of halls/sports halls in to allow the different groups to practice.
We haven't any near us in 2016 so am looking forward to the 2017 venues being announced.
