Calling Ideas for July 12, 2012

This is:

Yakety Yak #1 Song in USA
Yakety Yak, by The Coasters, became the number one song in the U.S.A., according to Billboard magazine. It was the first stereo record to reach the top of the charts.

Disco Demolition Night
This was Disco Demolition Night at Comiskey Park in Chicago, Illinois. Two Chicago radio DJs came up with the idea of having people bring unwanted disco records to the stadium. The spurned records would be burned between doubleheader games with the White Sox and the Detroit Tigers. Lead by the chant, "Disco Sucks!", most of the records weren't burned, but sailed through the stands during the game -- nearly inciting a riot. Some fans started their own fires and mini-riots. There was so much commotion that the ballplayers couldn't even finish the last game of the doubleheader; the White Sox forfeited.

Oscar Hammerstein's Birthday

National July Belongs to Blueberries Month
Must be blueberry season; time to eat a lot of blueberries.

Can we say "Blueberry Hill"?

There's also a Nitty Gritty Dirt Band instrumental called "Bluesberry Hill" that a lot of callers are using for patter.
