The Everly Brothers
Why They Split: The Everly Brothers despised each other when The Kinks were practically in diapers. During their years of success they were able to put up with each other, but by the early 1970s they just couldn't fake it any longer. They barely spoke for nearly a decade, but reformed in 1983 and toured off and on during the next two decades.
Last Performance: They hadn't played together in about three years when Paul Simon asked them to play on the Simon and Garfunkel reunion tour in 2003. "They basically came out of retirement for us," Paul Simon told Rolling Stone in 2004. "They met in the parking lot before the first gig. They unpacked their guitars — those famous black guitars — and they opened their mouths and started to sing. And after all these years, it was still that sound I fell in love with as a kid. It was still perfect." Things went so well that they did a brief European tour in late 2005. American dates were announced for 2006, but then canceled without explanation. They haven't performed together since.
Odds Of A Reunion: The Simon and Garfunkel tour and the quick European tour that followed really felt like a farewell. Don is 75 and Phil is 73, and they don't seem to have any desire to return to the stage. Sadly, we're going to say 25%.
