​Many Young Men Of Twenty Sheet Music Notes

There have been many different versions of the lyrics of this John B. Keane song. I have heard the song sung from a rake of ballad singers including Ronnie Drew of The Dubliners, The Wolfe Tones and by Johnny McEvoy and they all sing slightly different words. The  tune of the song stays the same nonetheless. This version of the sheet music  is in the key of G. The basic notes are included for beginners.
