The show that is available during June and July of 2018 is called Rockin Bubbles.
Performances are $250 for one show. Two or more shows on the same day are $225 each. These shows don't have to be at the same location! You can find another location, within a thirty minute drive, to split the cost with you. If you are sharing Brett with someone else, and there are mileage fees involved, he will split the mileage fees between the locations.
If the show is at a neighboring school or community center, then that's the address he needs.
