While not in a nursing home, I am in my early seventies and most of my friends in their sixties and seventies were listening to music that was popular in the sixties and seventies. This was the era of Jimi Hendrix, Cream, The Dead. A seventy year old was 24 at the time of the first Woodstock festival. They also may have been in their late teens/early twenties during the "great folk scare" and be fans of Dylan, Baez, Van Ronk. . .
