Well, I just discovered the AMA Motorcycle Hall Of Fame Museum's YouTube channel. These are short (about 1:30) biographies of riders from way back when up 'til recently, narrated by Dave Despain. I saw vids on people I actually knew!
This gent was the Greeves and Hodaka dealer in North Hollywood. I had a Greeves in the '60s and got my parts from him and Mrs. G bought a Hodaka Wombat from him.
Go over there and scroll through their lineup. You'll probably find something to watch.
