Factual Short Piece

My group and I have 1st had the idea to use the Cavern Club for our short factual filming. We think this could of been a really intresting piece for us to film and could get a lot of interviews and intresting stories.
Another idea we could of used was the night life of liverpool, although we have had difficulty trying to get hold of the A&E service.
After choosing our idea's we finally decided to use a band that make there instruments out of trash, they are called 'urban strawberry lunch'. They run a Tai Chi class every wednesday, so we decided to use this for our factual short film as the band do a lot of stuff for Liverpool. We plan to interview some of the people that attend the class, aswell as the Dr that runs it and if possible someone from the urban strawberry lunch band...
