RIP Jon Hager of the Hager Twins
The AP lists them as a comedy duo, but I recall they were more a musical team than comedy-based.
Back in the day the Hager Twins were a regular feature on Hee Haw, that hayseed-but-produced-in-Los-Angeles show that was required watching in Southern households.
I baaaaaaaarely remember a few members of my family (including myself) going to see them live at some local function. I was very, very small.
