Dennis Wilson composed “4th of July” in the early 70s during the Vietnam War (his co-writer was Beach Boys manager Jack Rieley). Carl Wilson sang the song. It was supposed to be included on the Surf’s Up album, but was withdrawn after a disagreement among the band members. Dennis Wilson drowned in 1983. “4th of July” was finally released as part of the Good Vibrations: Thirty Years of the Beach Boys box set ten years later. Carl Wilson died in 1998.
Note: Unlike most Beach Boys songs, this one was officially released only one time, in 1993 on the “Good Vibrations” box set, which is no longer sold by Capitol Records. The song was not included on the Made in California box set released in 2013.
Conan O’Brien offered additional commentary this afternoon:
Today, we Americans celebrate our independence from Britain while planning our escape to Canada.
