Going through old email I found this lovely description by my Mum of Extra Action Marching Band’s appearance in the Point Arena (Mendocino county, Northern California) 4th of July parade:

Toward the end came the Extra Action band from San Francisco —

impressively rehearsed, vividly brass- and drum- rhythmed, scantily

(though decently) clad, very very flashy.  They had silver lame`

flags and a lively routine which they performed now and then; the rest

of the time they kept the music going while members of the troupe

danced and wove among each other and out through the crowd — very

cheerful, very bold.  A group that gives anarchy a good

name.

Exactly so.
