Interestin', Joe. I know a different tune to those words. Definitely NOT Danny Boy. I learned it as a hymn, back in my misspent youth. Here's the words from the CyberHymnal, where they also have the tune that I am familiar with. Thanks for point the way to that site, I've been enjoying it since.
Blessings,

Words: Howard Arnold Walter, 1906. Walter wrote this hymn while living in Japan. He sent it to his mother, who forwarded it to Harper's Magazine, which published it.

Music: Joseph Yates Peek, 1911 (MIDI, score). Alternate tune: "Intercessor," Charles Hubert Hastings Parry (1848-1918) (MIDI, score).

Joseph Peek (1843-1911) was a Methodist lay minister.

I would be true, for there are those who trust me;
I would be pure, for there are those who care;
I would be strong, for there is much to suffer;
I would be brave, for there is much to dare;
I would be brave, for there is much to dare.

I would be friend of all--the foe, the friendless;
I would be giving, and forget the gift;
I would be humble, for I know my weakness;
I would look up, and laugh, and love and lift.
I would look up, and laugh, and love and lift.

I would be faithful through each passing moment;
I would be constantly in touch with God;
I would be strong to follow where He leads me;
I would have faith to keep the path Christ trod;
I would have faith to keep the path Christ trod.
