I sing because I enjoy singing,I have been listening to traditional music for so long,That I dont think it makes a difference now ,whether I learn a song from manuscript or a recording,in fact if anything I would like to learn it from manuscript,so that I can put my own style to it. What I do not want to do is sound like a carbon copy, of the last person I heard sing it on a recording. so I might listen to a source singers version of a song.or learn from manuscript,but because I have listened to source singers and traditional material for so long,I still sound like a traditional singer.DickMiles
