"Friends In Low Places" by Garth Brooks was written by two Nashville songwriters after a meal in a local restaurant. One of them forgot his money, but said not to worry, "I have friends in low places. I know the cook."
"Sloop John B" is a traditional West Indian folk song, and it was a huge hit for The Beach Boys in 1966. They tweaked the lyric, "This is the worst trip since I've been born" to "...I've ever been on" as a wink to acid culture.
