Thanks for uploading such a musical treasure, I noticed that it was marked with "American Airlines" on the tape label as you placed it on the machine, so I am guessing it was used for in-flight listening in the 1960's. These tapes are very rare.

I love this type of compilation, so popular in the Dawn of stereo sound!

I got this off the internet and put it on cd. Enoch Lights Project 3 series with some of the old Command stuff on it.
