Paul Simon is now nearly 70 years old and as he walked onto the Hammersmith Apollo stage last night it struck me that he is beginning to look like the little old man he will eventually become: still nimble, enviably trim, but nevertheless, he was noticeably older and more fragile-looking than when I last saw him five years ago. The second thing that struck me was a certain weariness in the opening songs - a mechanical quality to the playing, and a concomitantly flat atmosphere. The opening song, “Crazy Love Vol II”, was ploddy, while “Dazzling Blue”, from his new So Beautiful or So What album, just seemed listless. It was not an auspicious start to a show that had been rescheduled from the previous night after an unwell Simon had been on doctor’s orders to rest his voice.
