I saw them live a few times and recall one played what looked like a Les Paul Junior. That was the singer who also played some guitar. One of the lead guys played an Explorer. And the other lead players played like an old Melody Maker looking guitar. I was never close enough to see nuances but those were the body shapes. If I recall the lead guitar guys were named DOn Barnes and Jeff Carlisi with Donny Van Zandt being the lead vocalist who added rhythm guitar when there were dual leads.
They were a "funny" band in that they made the rep as a southern rock band but "Hold On Loosely" wasn't all that southern rock in the vein of what the Allman Brothers and Marshall Tucker brought to mind. And to a lesser degree Wet Willie. Wet Willie lost me when they started fighting about the name when the Hall family split in half. I preferred the half that Donna went with because she was hot...
