My KHJ/George Harrison experience would have been in 68-69 - before Tower.
I recall the record shop on Sunset looked more like a drug store and the LPs were in wall hangers.
My wife & I were very poor and spent a lot of time at beaches (Santa Monica, Malibu, Huntington) and walking Sunset/Hollywood Blvds and watched “the shows” - people and shops were quite a change in culture vs Ohio.
When I was growing up in Whittier, we usually went to Huntington when we went to the beach. But I preferred Corona del Mar, with its tide pools, and Newport Harbor, where one could swim without having to fight the surf.
