Apparently, Paul McCartney and I were on the same wavelength that night, because five songs into the set, he played a number that only a small, demented fraction of the audience wanted to hear. And yet there he was, jamming on “Temporary Secretary,” seemingly oblivious to the mass confusion created by the song’s mind-bending mess of synth bleeps and slashing acoustic guitar and McCartney’s robo-ranting about needing a woman who can be a belly dancer but not a true romancer. I loved it, and I loved how the people around me didn’t love it.
