Gordy's Drive In Theater
ADVERTS 1
I now have the perfect opening theme for my Drive-In theater!
I am going to take this recording (Henry Mancini's Mystery Theater Theme) and open the Drive-In with this. Then play either a Columbo Movie or a Quincy show first, then play an old movie like Hatari or The Bridge on the River Kwaii or a comedy like Blazing Saddles or Young Frankenstein.
I have plenty of movies to select from, so these are just some of the ones that top my list in my mind.
I have the projector and the big screen and a fair audio system to work with this, so now all I have to do is piece it all together.
I have to get 'er done this summer! I think it will be a blast!

Yep, I remember those days very well...which is about the last time NBC has a decent programming lineup.

Hey Larry,
Well, for certain the cartoons must be played first. I think it is a law, LOL.
I think I would be partial to Foghorn Leghorn and the guard "DAWG"... "Hey Dawg! Thar must be a storm a brewin', my corn is hurtin'".
Or Yosemite Sam or Huckleberry Hound... There is a lot to select from that will bring back memories.

Just in case you missed it, please listen here:

That really odd and mysterious sound that makes this music so perfect was created by an instrument called the "theremin".
You did not touch this instrument, you didn't pluck it, blow into it or beat on it. You simply moved your hands near it. Two antennas picked up the capacitive/inductive reactance and altered the tone and volume.
This instrument was designed and built by Leon Theramin in 1918! (Patented in 1928). Not only did he invent this unique instrument, but he is also accredited with inventing the technology of interlacing for modern video technology!
Way to go Leon!

Principles of Operation
Operating principles
The theremin is unique among musical instruments in that it is played without physical contact. The musician stands in front of the instrument and moves his or her hands in the proximity of two metal antennas. The distance from one antenna determines frequency (pitch), and the distance from the other controls amplitude (volume). Most frequently, the right hand controls the pitch and the left controls the volume, although some performers reverse this arrangement. Some low-cost theremins use a conventional, knob operated volume control and have only the pitch antenna.
The theremin uses the heterodyne principle to generate an audio signal. The instrument's pitch circuitry includes two radio frequency oscillators. One oscillator operates at a fixed frequency. The frequency of the other oscillator is controlled by the performer's distance from the pitch control antenna. The performer's hand acts as the grounded plate (the performer's body being the connection to ground) of a variable capacitor in an L-C (inductance-capacitance) circuit. The difference between the frequencies of the two oscillators at each moment allows the creation of a difference tone in the audio frequency range, resulting in audio signals that are amplified and sent to a loudspeaker.
To control volume, the performer's other hand acts as the grounded plate of another variable capacitor. In this case, the capacitor detunes another oscillator, which affects the amplifier circuit. The distance between the performer's hand and the volume control antenna determines the capacitor's value, which regulates the theremin's volume.[9]
Modern circuit designs often simplify this circuit and avoid the complexity of two heterodyne oscillators by having a single pitch oscillator, akin to the original theremin's volume circuit. This approach is usually less stable and cannot generate the low frequencies that a heterodyne oscillator can. Better designs (e.g. Moog, Theremax) may use two pairs of heterodyne oscillators, for both pitch and volume.
