Never marched, ran, or sang in HALO training - however, we did have some HALO cadences we'd sing sometimes when doing formation PT as a B or C Tm. One had verses for Ranger, SF, Black Hats, SCUBA, and a HALO verse which went something like this:
I saw an old lady walking down the street She had a chute on her back, freefall boots on her feet The chute she wore nearly blew my mind 'Cause that chute had no static line. I said, "Hey old lady, don't you look cool... Tell me granny what do you do." She said, "Sonny, sonny, ain't you a jewel... I'm at the Army's HALO school." I said, "Granny, granny what do you do there?" She said, "I fall out of airplanes and fly through the air. From thirty-three grand to opening low HALO infils are the way to go." I said, "Granny, granny ain't you too old? HALO school's for the young and the bold." She said, "Sonny, sonny don't you be no fool, I'm an instructor at the HALO School."
