Saw a youtube video of a Family Guy episode saying that “Fortunate Son” was overplayed in Vietnam-related media. I only remember hearing it in Forrest Gump. Before that, thanks to Apocalypse Now, the go-to “Vietnam song” was the Stones’ “Satisfaction.”
But “Bad Moon Rising” is a great Credence song.
The other “Vietnam song,” also thanks to Apocalypse Now, was “Ride of the Valkyries.”
