Definitely Lavalle Houser on bass. I remember now... Met him through Alan, used him for a "free funk" band/gig and then recommended him to Dennis.
Great player, super nice guy. Sad to say, I totally lost track of him. Hope he's alive and thriving today!
Back then, there were so many different layers/pockets of who was playing what where in Dallas, . So if you got a rec for somebody you were unaware of, you took it. If it worked out, hey, more pieces with which to solve the puzzle!
