"Can you imagine us years from today, sharing a park bench quietly?/How terribly strange to be 70," Simon and Garfunkel sang on their classic 1968 tune "Old Friends." Well, Paul Simon and Art Garfunkel both turned 70 last year. They aren't just sitting around park benches together throwing crumbs at pigeons, though – both have released new music in the last year and gone on solo tours. For Art, it was his first time playing shows since a major vocal ailment forced the cancellation of a Simon and Garfunkel reunion tour in 2009. He seems to be pretty close to recovery these days, and it's time to make up those gigs. Paul has recently said he wants to tour with Art one last time, and Art has made it clear he's down. So what are they waiting for? If they call it a farewell tour, they'll basically be printing money.
