A little change of subject.  Found this very interesting - from YouTube

.
Thank you, Merry, for posting that!
.
In Austria the Radetzky March is sometimes used for an ENCORE at concerts, and everyone loves it, especially the musicians.
.
It has deep roots in national patriotism, which is here augmented by the drummer strokes, precise movements and stark discipline.
.
For each minute you see performed they had to drill for many hours.
.
EVERYONE begins their step-offs and changes instantaneously. Very impressive display.
.
Seeing the goose-stepping in dress white trousers is a sight to behold. You'll NEVER see the USMC do this!
.
Until you try it it's impossible to know how difficult it is to goose-step while playing an instrument.
.
For those who know tempos, they were marching at Andante, mid-range, at metronome = 92.
.
One rider actually got his horse to keep in step. Now that's an achievement!
.
I find their use of WWI/WWII ceremonial rifles and traditional swords edifying.
.
It wouldn't have the same feel if the infantry carried AK47s or Uzis.
.
And bazookas, tanks and missiles would be ridiculous.
.
If any members here who know Spanish could translate a few lines of the announcer's words that would be great!
.

.
As a point of reference, here's the Vienna Philharmonic led by Zubin Mehta, i.e., ideal conditions:
.

.
BTW this tempo is m = 108, as fast as Andante gets. This would be too fast for goose-stepping. 
.
Other performances of this march on YouTube use a faster tempo, into Moderato, which is too fast for any march, really. 
.
Mehta gets it just right.
