Try not to get TOO simple. Sometimes clarity of lyrics can get lost. You can usually rent a small digital recorder from a music store for very little money (compared to going into a professional studio) and your words will come out clearly. I've enjoyed McGrath's songs, but I sure wouldn't complain if I heard the lyrics a bit cleaner.Those little mini-disc recorders also do a fine job with clarity. A good quality mike can make a HUGE difference as well.
