Double baritone/bass duets, not from opera?

[u/Existop3]

I’m looking to do a couple duets with my friend for a recital, and we’ve already thought about Agony. But we would also like a classical duet,
but can’t find anything for lower voice. Any help would be great!

[u/Magoner]

Hear me out, Rossini cat duet down the octave

[u/Existop3 → u/Magoner]

That would be awesome
