Here's something that happened exactly 40 years ago, but which I just learned today:
The Broadway musical Billy, with songs co-written by bubblegum music master Ron Dante, closes after one performance.
That's from the blog The Hits Just Keep On Comin', and I'm sure the blogger knew, but just chose not to mention, that Ron Dante was more or less the entirety of the Archies. (He also chose not to mention that his blog was named after a Michael Nesmith solo album.) Today's entry is simply a compendium of stuff that happened on March 22, 1969, which I find very useful. It roots you in history to know the Lew Alcindor's last college game for UCLA was on the same day as John and Yoko's first bed-in for peace, in Amsterdam.
The Hits is written by a DJ named Jim Bartlett, the sort of guy who's been from town to town, up and down the dial. He also points out things like the fact that Dusty Springfeld's marvelous "Breakfast in Bed" was a Top Ten hit in Louisville, where Alcindor was playing in the NCAA tourney, although it was barely a hit at all nationwide. I wouldn't even know how you'd find that stuff out.
I found the Hits via the blogroll at Scraps' site. If you like OPC, you'll probably like it too.
