As a child during WW II my favorite song from that era is "There will be blue birds over the white cliffs of dover."
Having grown up in Nashville our teenage years (the 1950s and early 1960s) song was Pat Boone's "Love letters in the sand" a smooth tune well sung by Pat, who my late older brother sang with in Pat's original Quartet before Pat Boone became a hit as a single singer.
During my undergraduate college years, 1959-1962 a sort of country swing tune we all liked was "Silver threads and golden needles cannot mend this heart of mine."
During the Vietnam War, while I was on USAF active duty in Pakistan, not in Vietnam, I liked Nancy Sinatra's song "These boots were made for walking."
In our later years, now, I still like the country and western song "He's in the jail house now."
I doubt many youngsters on this site know of most if any of these songs.
