throughout the week I was remebering the JLU episode when Batman had to sing in order for Circe to remove her spell on Wonder woman.
For all of his great strengths, Bats was also a great singer.
And for his deep tenor voice and command of the language and form, I have to guess Doom must also sing well, if he devoted himself to it. (Would his mama have taught young victor to sing?)
this proves it. Just not the genre I was hoping for.
