• Tubas include Sousaphone, B Flat Baritone Horn (my instrument), Euphonium).
• Each Christmas there are over 150 celebrations called TubaChristmaas, held in public places, e.g., at a Malls. I have participated.
• Many of the players are actually Trumpet players who are able to play the Baritone Horn (same treble fingering)
• There are many organized Tuba groups that might be called upon to play at PD sponsored Tuba happenings, ad hoc,  and promoted by local PD Support Groups.  I could research the names of key Tuba groups, and supporters, e.g., the Band directors Association of America; "The Big Red" have 100 marching Sousaphones.
• Venue: Malls, front steps of state capitals, also county seat, Rocky Balboa's front steps at the Philadelphia Museum of Art.
• Chris Browne, cartoonist, Horrible Hagar, had a strip. as follows: Hagar to Lucky
• Eddie, "It's a tough world out there."  "You have to blow your own horn!"  Eddie, responds, "What if you're not musically inclined?"
• Why Tuba?  There is a tradition, structures are in place, the ultimate is the 500 plus Rockefeller  Center Christmas Tubas.
• Joshua   blew the trumpets, marched around the city, and the walls came tumbling down.
• Finally Tubas attract attention, have a great soiled sound which many people have never heard, especially as played by a virtuoso of the instrument,
• When in the year?  Music?  Songs off Americana, or songs of hope..
