Shane's vocal abilities these days seem to have little to do with his lack of teeth and everything to do with what shape he is in on the particular day (as well as how much of an effort he wants to make, of course). There is this dreadful recording of The Town I Loved So Well with Lancaster County Prison in which Shane's vocals are so utterly horrible they make you wish he'll never record another song. But then again, on the recent Fairytale Of New York with Katie Melua he sounds fine. His vocal abilities has always had it's ups and downs I guess, only these days the downs are, honestly, really bad.
Whether or not he is capable of making another album is anybody's guess and I see no point in speculating. Time will tell.
