Forgive me if you already know this....
Retro TV holds the rights to access a bunch of Universal Studios TV programs and they are running Jack Benny at 8:00 am on Retro TV in the Arizona market. I noticed on their website that it runs at different times in different markets. For example in West Virginia, it runs late in the evening and they show two episodes back to back!
Here is a link to their programming schedules in various parts of the country. IJBFC members will have to check their State and local cable schedules to see when and IF they are running Benny in the area...
