EXTRA CONCERT PRACTICE: URGENT URGENT

I am having a terrible time trying to find days to suit most people: The Junior classical and junior novelty will be on Saturday 24th as stated earlier. Novelty Group from 10.30am to 12.30 (This includes Lavendar and Onions and Petunia) & Classical Group from 1pm to 3pm..Bring your lunch with you ..HOWEVER the Senior Classical Group is proving more difficult. With School Camps, Mackay Eisteddfod and other committments it is becoming a nightmare...Its has been suggested we try Monday 19th October as this is apparently a Student Free Day for all schools. We would go from 12.30pm to 3.30pm and then my normal Monday classes after that. Let me immediately if this isn't going to work. Thanks Mrs. Dx
