"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."
When "Nothin' On You" reached #1 on the Hot 100, B.o.B became the first American act whose name is a palindrome to top the chart. The other two who did so prior to the Atlanta rapper were both Scandinavian groups - ABBA and A-Ha.
