Here’s an MP3 that in 3 minutes and 10 seconds attempts to summarize the last 30 years of KGO NewsTalk 810. On it is Joe Starkey’s dramatic call of The Play … you know, “the most amazing, sensational, dramatic, heart rending, exciting, thrilling finish in the history of college football.” It also includes Stan Burford reporting on Oct. 17, 1989: “I’ll do it slowly and I’ll do it once. East Bay, Cypress Section, double decker of the Nimitz has collapsed. Upper deck onto the lower deck.” And it has the sign-offs of KGO’s best known talent over the years. The sound bite is part of the station’s celebration of its 30th year as the Bay Area’s top rated radio station.
