Duetto buffo di due gatti {
wiki} translates as "humorous duet for two cats". Just
try not to giggle as two members of a boys choir perform this number at a concert in Seoul, South Korea. Then compare that to an animated version with two cats.

This composition is ironic, so it gains a lot being interpreted with a straight face (even if it's difficult, considering the second boy's smirk and the gesture of the pianist). What's the point of making it a goofy show ? Would you like to see them wearing fake tails and pointed hears ?
And yes, it's earnest. Considering the technicality of the performance, it's normal, I think?
My cats apparently have a deep interest in French boys' choirs.
