Well I am happy to have you back and I too know how devastating it can be to loose your voice, I myself have been without mine this whole winter - it's driving me insane lol.
I understand changing the register to suit your new range, but I have to say you came back with a vengeance and I loved every moment - you have an incredible voice even when reduced in range (I should mention it's only obvious to you, it doesn't reflect in the performance at all).
I loved that song and really can't stress enough how catchy that tune is, I can see people wailing out in their cars on the way to work to this song - a really great performance and song, so thrilled you shared it!
