Here's Max Gail from Battle of The Network Stars. Check out Donna Dixon and Scott Baio briefly checking out his ass between 0.56 & 0.58. Classic. You have give him credit. He had a nice meaty ass.
I got to know Ron Gless who was also on Barney Miller and I asked him about the show. He wouldn't give any names but he said practically everybody on the show was gat. So the chance of Max being is pretty good.
