Were it not for the Grim Reaper, two celebrated musical couples would be celebrating wedding anniversaries today. Country music superstars Johnny Cash and June Carter (soon-to-be Carter Cash) tied the knot on this date in 1968 in a Franklin, Ky., church. The bride wore light blue; the groom wore (duh!) black. Their relationship was the basis for the celebrated biopic Walk the Line, which showed the couple's rocky patches in all their glory, as well as their dedication to each other. The couple had just one child together, John Carter Cash (born in 1970). The couple managed to put their problems behind them and remained married until June's death in May of 2003. Cash passed away five months later. June co-wrote (with Merle Kilgore) one of Johnny's biggest songs, 1963's "Ring of Fire," which is said to have been inspired by her conflicted feelings for Johnny.Also on March 1, Punk poetess Patti Smith and former MC5 guitarist Fred "Sonic" Smith were hitched at the Detroit Mariner's Church in 1980. They'd met in 1976 in front of Detroit's Lafayette Coney Island, a famous hot dog joint, introduced by her guitarist, Lenny Kaye, before Fred's Sonic Rendezvous Band was set to open for Patti's band. They were a couple two years later and after marrying, the pair pulled back from the public eye to raise their children, daughter Jesse (born in 1987) and son Jackson (in 1982), who went on to marry The White Stripes' drummer Meg White in 2009. In 1988, Smith released Dream of Life, a collaborative project with her husband and her first album since 1979's Wave. Smith died of a heart attack in 1994, leading Patti back to New York City and back to music. She toured with Dylan in 1995, then released Gone Again the following year, marking her total return to the music world (she's had four albums since). Here's "Dancing Barefoot" from 1979, a song Patti dedicated to her new beau, Fred Smith.Click on for Born This Day featuring … OMG, Justin Beiber is 18 today!
