This request is for an old song from the 1930s by Daniel A. Lord S.J. which is a march of all things, rallying young Catholics. The Catholic Action movement is way before my time, but I do have an enormous Catholic Action Bible. It has wonderful portraits of all the disciples and they are a lot of extremely European looking gents except for Judas who is a crude caricature of Jewishness.
I’m not sure what role a song like this could have now as its martial style seems from another world. Godsongs has the text and the sheet music is available here.
I had to guess the chords and BIAB has limited facilities for marches:
Indeed, it is quite unusual. I researched it because someone requested it in 2012, and have been surprised that hundreds of people have searched for it since then. I’d guess that most people looking for it are individuals remembering it from their own youth, though, not liturgical musicians wanting to use it today.
