Sacco, under the tutelage of family members, was a traveling musician as a child, playing piano and performing as a soprano vocalist.

He then entered the military and studied while in Frankfurt under Wolfgang Niederste-Schee; he also performed on piano and organ and played clarinet as a member of the 4th Infantry Division band.
