The Everly Brothers
The Everly Brothers were more or less retired in 2003, when Paul Simon managed to lure them back onto the road for a Simon and Garfunkel reunion tour. "They hadn't seen each other in about three years," Simon said. "They met in the parking lot before the first gig." Their brief sets in the middle of Simon and Garfunkel's headlining performances were transcendent. Fans got very excited when the Everlys announced their own tour of England in November 2005, and there were even dates on the books for an American run in February 2006. Sadly, those were cancelled with little explanation, and Don and Phil Everly haven't played together since. The brothers are rarely seen in public these days, although Don did perform "Bye Bye Love" with Paul Simon in Nashville last year, and Phil sang at a Buddy Holly tribute show a few months after that.
Barrett Scale: 4. The Everly Brothers lead very private lives, and it's extremely difficult to get them to agree to an interview. (Believe us, we've tried.) Both still seem to have pretty strong voices, and they could probably tour if they wanted to. But for whatever reason, they're opting not to.
