Hi guys, I need your help.
I'm pretty cool with playing this song in the C with a capo (like Justin), in the C without a capo, in the A, etc. If only I had to just play it, it would be sweet! ...but I have to SING it too

So that's what I'm after.
My singing range would be probably somewhere between G#2 and D4 (I know it's bad, I'm working on it too), and I'm not even entirely comfortable with the bottom and the top of this range in actual songs.
Question 1: That's my main question. What the hell is going on after the second chorus?!
"Rent a flat above a shop, cut your hair and get a job...". In the key of C, I can sing the song perfectly up to this point, and I LOVE it (I think I sing it an octave lower in this key)... but right here, on
"Rent a flat...", I can't figure out what the vocalist (Jarvis) does! Does he start singing higher? It seems like he starts "crying", but since I can't seem to sing along with him properly, perhaps he changes the pitch too
Question 2: If I change the key of the song down to make the
"Rent a flat..." bit easier, I should change it to A, right? So just play like Justin without a capo?
Again, I like it in C more, so I hope someone knows what's that
"Rent a flat..." bit is all about, so maybe I can learn to sing it in C

Perhaps if you told me the notes the vocalist sings, so I know where they are relative to my range?
Question 3: On a different note, I remember Justin saying that Fmaj7 can be played instead of F in the key of C, but in this song, when played with open chords (C-G-F), Fmaj7 sounds a little weird, no? Or it doesn't sound weird?
Cheers.
