Thanks for taking the time to reply, fellas. I appreciate it. I plan on taking some lessons, maybe investing in a course sometime soon, but as mentioned above at the moment I'm trying to get my breathing right. When I focus on proper breathing technique I do notice an improvement in my singing but I'm a long way from doing it automatically - and as many of my tunes have quite a complex (for me) guitar pattern I tend to focus on that rather than the breathing. Still, one step at a time :-)
