Yes, BK solved a good puzzler for me yesterday. I'd been scanning some color slides I'd taken in L.A. in the late 1970s, and I had two that showed some outdoor performance or presentation that was set up to take place in Century City, between the Plitt and Shubert theaters. I didn't remember these two photos at all, even though they're obviously mine. But I also knew I hadn't watched whatever the event was, so I thought BK might have a clue. We had a date to go on, and he found the announcement solving the puzzle in the LA Times.
The whole discovery is a bit of serendipity: Stephen Schwartz's The Magic Show was on stage at the Shubert (sadly, I never saw it) and there just happened to be a Friday the 13th coming up, so they put a stage setting and two pianos out there in the plaza and were about to hold an amateur magician's contest that Friday at noon, and have a few songs performed by the cast of the show. I have no idea what I was doing there on a Friday during the day, but I walked by and took those pictures, and I'll just bet there are very few others in existence. BK was busy with The First Nudie Musical at the time (this was in June 1975) so he didn't see it either. So once again, newspapers.com saves the day.
Here's the better picture of the two. The other one thankfully gave us a hint of what was playing at the movie theeder then, so we had a date to go on.
