Rough sketch of a song in B natural, I guess. I'm guessing because A) I tune down a half step so working out keys gets a bit fiddly for me (and the tonic of the song is a C shape on guitar, but a half step down, so you know...), which leads me to B) I'm not that great with my music theory. I'm pretty sure there are some chords in here that are not technically in the key but... whatever. Puppy.
