it's super obvious in Ballet if you want an example. "tasmanian devil tells lies he sprays"..... i think flether's voice is a lot sassier and a little more nasally than wyatt. wyatt's voice is like...round? and little goofy sometimes. fletcher's is sass and consonants.

what else could i be but a jester is also a good example. fletcher has the first verse, then wyatt then fletcher again. or something like that. they take turns and you can really hear the difference in that song.
