Twice, I've composed a long post only to hit some wrong key and have the whole thing disappear. Third and last try, and if I screw this one up, tou'll never know.
The most ubiquitous bugle call -- at leasr in the US, at every baseball stadium that boasts a sound system --derives from all thos eWesterns we were raised on in which the cavalry rides to the rescue and at the crucial moment (the wagon train is just about to give up hope) the troop commander utters the immortal line, "Bugler, sound the CHARGE!"
Now when the team need a rally, the organist/tape plays the stirring notes and the loyal fans scream, "CHARGE!" I'm sure this hasn't spread to cricket, and I've never herard it at American football games, but is there such a practice at Rugby, FA or Australian Rules games? Yet?
I'm surprised that some enterprising promotion man hasn't figured out how to co-opt "Taps" as well, maybe to mark the end of a lost game or season, or to mock the visiting team if it's been shellacked.
