The entire Sousa library is available inclding the conductor’s score on line. There are even playable music files in case you don’t remember how all of them go!!

I’d offer my insurance expertise but I only do personal lines, nothing institutional...

No offense, it’s bidness!!

For a long time here bands have been required to have $1M of liability insurance in order to rent a space. It's in case someone trips over something and breaks their whatever, and decides to sue the venue.

I got very reasonable liability insurance for my bands through a local trombonist in Virginia who is an agent for Erie.

The performing group is responsible for any damage that THEY cause. If somebody trips over a power cord, or you trash the place, or break a glass door - I did that once on a gig, carrying an amp through a door and it slammed shut on the metal corner.
