At least part of the fervor behind the applause that greeted Paul McCartney‘s visit to Jimmy Kimmel Live was his appearance. Slim, dark-haired, agile, quick-witted — this is what a 71 year-old in good physical shape looks and sounds like in 2013. As opposed to, say, your typical 71 year-old, madras-shirt-wearing tourist from Phoenix. Not so much about “denying the biological reality” but a vigorous pushback. At the same time I haven’t the slightest interest in listening to McCartney’s New…sorry. The last McCartney act that got me out of my chair was the Nirvana performance. Here’s a clip from last night’s Hollywood Boulevard set.
