KT, Janet Lee (no relation to me that I know of, albeit I have a niece with the same name prior to her marriage) stated as much. All I can say is if you want to play altissimo, be my guest and go there. After a 40+ year layoff I began my comeback in 2006 and in 2009 recorded multi-instrument ( I play all parts) rendition of Edward T. Paull's Charge of The Light Brigade with parts up there on the "ceiling" that I played on a normal Bb trumpet (I didn't have my Schilke picc yet). You figure my age then, if I'll be 75 by the end of this month. But that was before my triple bypass heart surgery.
Can't remember, and who really cares, but I may have played it on my Lead 342 Assymmetric mpc, While this song is certainly a military theme, I wouldn't place it in the genre of a march, more just as an epic. Edward T. Paull was a prolific marketeer of sheet music, but there is no corroborative evidential finding that he composed music himself. Too, yes this song is very old and in the public domain and the piano sheet music was borrowed from another.
