i remember an all metal banjo, thinking first then the guitars, but not clear. i was around the Texas scene & think that is where the banjo was with - Stevie Ray or the ZZ guys/could have been with a number of those back then. ZZTop loved old cars & metal! Butshit, so did Willy Nelson, Stevie, Huey Lewis......most of that crew & it bled over into Seattle/Tacoma grunge & out n about. The music scene was smaller & homeboy like back then.
