1955 Elvis in San Diego
This is a very nice period piece that recalls the segregated hours for r&b broadcasts on white radio stations (day for white, black at night) pretty much standard broadcast code throughout Southern California at least, and another reason Frank liked Elvis (because Elvis was banned from San Diego performances after his first and only show, which is described in remarkable detail aided by historic hindsight, much like the Deacon was banned in Los Angeles when I was in that vicinity).
