I don't know his Mudcat name, but there is a 'Catter who probably knows a good deal about the info you seek because his band is named Hal & Tow. Perhaps Kendall can PM him for you to see if he can assist you, if answers to your post do not afford you satisfaction. If you need to, refresh this after a day or two and, hopefully, I will pick up on it if Kendall does not.
