Of course in my youth there was no instant coffee, tea, potatoes, etc. In music, the change is drastic. Songs were recorded on 78's, 16's, and 45's. Later they were replaced by the eight-track cartridge, then cassettes, nowadays we have CDs. Messages and lyrics in some songs have become obscene.
Music continues to change with the times.
And of course, people also change as far as beliefs, ideas, etc. I remember in my youth that I could not enter in some public places such as restaurants, barber shops, and theatres. As late as 1964 when I graduated from HSU, I was told to seek employment in South Texas because I would not be hired in Abilene or North Texas. It is good to reminisce. It should help us to appreciate what we have.
