Can I not remember movies any more? I know I've seen North by Northwest, but didn't remember the climactic scene at all; Barb says we watched Dial M For Murder together, and none of it seemed familiar at all.
The very first item was two movements from the Psycho suite for strings, a favorite of mine; the shower music is stereotyped as shrieking, but it's actually got a neat structure, beginning on the violins and then moving down through the violas to the cellos. The music for North by Northwest is also a lot of fun: a peppy motif is repeated over and over, driving the scenes relentlessly onwards. The second half began with a collage of the Hitchcock family's home movies with the trailer for North by Northwest, accompanied by Gounod's "Funeral March of a Marionette", Hitchcock's theme tune.
Attendance was pretty sparse; the orchestral-level seats were only half-full, and the loge seats were maybe three-quarters full. The scattered rain that fell early in the evening also probably kept away people with lawn tickets. That's a pity, because the rain was never very heavy and stopped completely early on, and didn't spoil the concert at all.
