It’s ’70s night at Dodger Stadium, and this week’s postgame fireworks show — they’re planning on having one after every Friday night home game this season — is going to be accompanied by ’70s music. I just saw Emma, who posts comments here often, down in the field-level seats wearing a crazy ’70s afro wig. Right now, tonight’s anthem singer is in the press box rehearsing with Nancy Bea at the organ, so we’re hearing The Star-Spangled Banner at the same time they are playing that one ’70s song — it goes, “Wo-man, take me in your arms, rock me, baby,” so if you know who sings that and what the title is, feel free to post — so we’re hearing those two songs on top of each other. Delightful. Now they are playing Dust in the Wind, and the woman is rehearsing the anthem for a second time. Even more delightful. … By the way, someone from Cincinnati emailed me the other day wondering if Clayton Kershaw is related to Sammy Kershaw, the country singer. I checked with him, and he said no. But he did say that some of his teammates have taken to calling him Sammy in the clubhouse. … Now they’re playing Show and Tell. I don’t know who sang that, either, but it could be Lou Rawls. Wait, no, I just looked it up on Google. It’s Al Wilson. I’m going to get out of here before that woman starts singing the anthem again.
