Yeah it makes me sad too actually. it's one of my favorite songs I've written. I have written keyboard and sing to it past the chorus but after that I'm still writing. makes me wish I could go back sometimes.
Same to the going back... I so want to be 14 again sometimes- I think that was the best time- back before everyone started falling out and revising for exams and everything... Hope you get to finish the music as the lyrics deserve it.
