I have just been watching on DVD the 1993 documentary “Theremin: An Electronic Odyssey” which is quite fascinating, especially for the footage of Terman himself, but I stunned by the blatant BS in the segment with Brian Wilson discussing his hit song Good Vibrations. There is Wilson with a Theremin in front of him waxing lyrical about it while over him we have a clip of the Beach Boys with the instrument that was actually used -- i.e. the Tannerin -- clearly being swiped along its “keyboard”.
Here’s another clip (also wrongly titled):

I can’t understand how director Steve Martin allowed that erroneous segment in the film to stand. I don’t know if Wilson went on to explain that the Theremin wasn’t used and that bit was excluded from the film, but director Steve Martin -- who ought to have known the Theremin inside out after researching material for the film -- went ahead and allowed his audience to believe a fallacy, and made Brian Wilson look like he didn't know what he was talking about into the bargain.
