If I'm not mistaken it was the 1941 revision of FM 22-5 that streamlined the drill and ceremonies taught to troops by eliminating much of it from doctrine. By then it was probably considered to be a non-essential use of training time, and it had been a long time since drill and ceremonies were used to deploy troops in tactical situations. (That being said, traveling formation is still column and fighting formation is still line.) I've read of Civil War versions of "Cannoniers' Hop," with its calling out of numbers and so forth.
