The title is definitely "Bandolero", but not the Mariachi version of the same name.

I found a songbook ("Songs of Yale") that has it, at:

Also, a German barbershop CD at:

I'm in the process of contacting some of the members of my college singing group to see if we can locate it. Interestingly, I must have it somewhere in my reel-to-reel archives, as I helped them record a demo tape in the early sixties. Doubt if I can find it, but I'll try.

Finally, I've got my barbershop maven on the case. Stay tuned!
