If this is the last photo of Prince ever taken, it fits.

Word that Prince was so ill his private jet staged an emergency landing scared the hell out of fans worldwide last Friday.Reportedly suffering from an enduring case of the flu, Prince, 57, had played back-to-back shows in Atlanta just the night before.Evidently Prince was about as keen on sitting in a hospital bed in Illinois as you'd think. Within hours, he'd got up and left, flying back to the Twin Cities for some rest at home. But Prince doesn't do rest.On Saturday he was up and out for Record Store Day, tweeting that he'd hit the Electric Fetus store in Minneapolis to grab Stevie Wonder'salbum. And later that night, the Purple One even showed up on stage at Paisley Park, telling fans he was fine, and that they should "wait a few days before you should waste any prayers."Prince played a little piano for his guests and showed off a new custom-made purple guitar, the Star Tribune reports , but he didn't play it and he didn't sing.Sometime Saturday, between the record store appearance and his onstage surprise, a candid photo surfaced online that might be the last publicly taken image of a man who tried, and largely succeeded, to maintain as much privacy as an internationally beloved rock icon could possibly expect.The photo doesn't show his face but is unmistakably Prince, purple jacket and all, riding his bike along the street in Chanhassen, heading back down the block to Paisley Park.Not off into the sunset, but back toward the light. To the place he worked and made his home. Among us, and unlike anyone.Ride on, Prince. We might never catch up to you.
