In the battle of Coke ( KO) vs. Pepsi ( PEP), the former seems to have the upper hand when it comes to music (and we speak not of that powdery substance caked on Neil Young's upper lip in The Last Waltz). Name-checking the pride of Atlanta goes all the way back to the era of boogie-woogie and the Andrews Sisters imploring the Greatest Generation to enjoy Rum and Coca-Cola. If you were a child of the '70s, you probably recall the soft-focus, hippie-vibe TV commercials that featured The New Seekers singing I'd Like to Buy the World a Coke. In a rare feat of reverse product placement, the band topped the charts in 1971 with a reworked version of the jingle, I'd Like to Teach the World to Sing. The Beatles, at John Lennon's raunchiest, mentions "he shoot Coca-Cola," a reference the executives might not appreciate much if they really thought about it. R. Kelly's Same Girl pairs Coca-Cola with Dodge Durango, and 50 Cent mentions the beverage in both I Get Money and Disco Inferno. There was also a lost opportunity. The Kink's gender-bender hit Lola originally had the line "where they sip champagne just like Coca-Cola." Due to a BBC restriction on such commercial plugs, it was changed to "cherry cola."
