Thanks for the hints. I'm in the Sheffield area mostly but will be in Manchester for the next 3 weeks if anyone knows any area? Singing or playing would be awesome :)

I think what I need to do more than often is to listen to a few versions of a song. Don't get too attached to prevent relative pitch screwing me over. Or sit with a guitar and just sing it while doing crazy things. If it works when writing my own stuff it'll work with arranging.
