Yes he is good isn't he? His brother, as I am led to believe used to play with him in earlier years, and I think still does on occasion. I seem to remember Tommy saying in an interview some time ago that his brother was the lead guitarist whilst he played Rhythm! Don't know for sure though.
And that guitar he gets such wonderful sounds out of - is a MATON. Made in Australia, and IMHO, as good as they get.
