Change of Plan for the Band Sections of my Music Video

I had originally planned to film today (Tuesday 6th December) and also next week (Tuesday 13th December). However, I did not get a response from all cast members as to whether or not they would be free. Also, On the 13th I have a Duke of Edinburgh award meeting which I need to attend; and therefore that date would not have happened anyway. I was talking to Scarlett Colson, who is in the media class and is also having an area of performance using the same location. Two of my cast for the band are also in Scarlett's, and therefore we thought we could film at the same time, in the same location; and take it in turns. This would save time for both of us, and also for the actors as they would only need to take one day to do this. We also thought that we could do this on one of the first Saturday's in January; and we are currently trying to arrange this with the cast, and any teaching staff which would need to be informed that we would be using the school drama hall on a Saturday. The two cast members which are in both of our videos will need to bring a change of clothes so that they have the correct costume for both me and Scarlett.  As well as making it easier for me and Scarlett and the cast members, it would mean that all of the filming could be done on one day, and we know that the drama hall will definitely be free for use. I have contacted all of the cast members to inform them of this, and they have all agreed except for Tommy and Joe, who have not replied yet. When we know of a date which they are available, we will then get permission and make the arrangements with the props and location in the school. (Music faculty for the props, and drama faculty for the use of location).
