The Theramin was also used on The Beach Boys' recording of Good Vibrations. I built one of these devices way back in the 60's when analogue synths were just starting to appear. It takes a great deal of skill to play - something which I never really mastered - I eventually dismantled it and re-used the components. However, it was quite an interesting project.
