I know it's not related to studio wrestling in the 1970s, but during the same time I got interested in pro wrestling, I also loved watching Los Angeles Thunderbirds roller derby which came on right after wrestling at 12:30 AM on WLOS-13 out of Asheville, NC. (I have posted about this earlier.)
On this page I plan to collect some video from those days that is on YouTube, perhaps some photos, too.
But THE place to go for all things T'birds is Scott Stephens' excellent history site. Click the graphic or link below.
