Permission for the Use of Instruments

We wanted to make the band scene as realistic as possible so we wanted to borrow some instruments. We had an idea plan of two guitars and a drum set or a guitar, drum set and a triangle for the comical purposes. We were unfortunately unable to use the drum set or triangles. This is when we had the idea to have  a xylophone and two guitars and we have borrowed two microphones for the main singer and the backing singer.
