Music, athletics, politics…

Would you guess a Castro Valley summer opera production would be the coincidental lead-in — and link — to the Aug. 8-24 Olympics in China, the Aug. 25-28 Democratic nominating convention in Denver, and the Sept. 1-4 Republican convention in Minneapolis-St. Paul?

It’s true.

Trinity Lyric Opera is presenting “Nixon in China” on July 18, 20, 25 and 27 at the Castro Valley Center for the Arts.

The opera chronicles the 1972, first-ever visit to mainland China by a sitting American president — Richard Nixon.

Nixon, by-the-way, won the Republican nomination for president 40 years ago.
