No. Just no.

We read that the next two lines come from a deep male voice (presumably Tam Amber) but also that it comes from a different place in the crowd. With Maude Ivory being described as around nine years old, she wouldn't be eligible for the reaping yet, and we get it confirmed from SOTR that Tam Amber would already have aged out, meaning the two would presumably be standing together (and potentially with Barb Azure, I can't remember if we get a confirmed age range for her). The only members of the Covey that would be standing separate to that group would have been Lucy Gray, Billy Taupe and Clerk Carmine, being the three we know to be of reaping age (Clerk Carmine being twelve, quite probably with a still unbroken voice lending towards Snow's difficulty identifying it). Which leads me to believe its Clerk Carmine (and also would be interesting in that it's potentially the only time we hear of both him and Tam Amber singing).
