Yes, that’s 76-year-old Norman Greenbaum performing his monster 1970 hit Spirit in the Sky just a few years ago. The song was on the charts for 15 weeks and apparently the royalties have allowed him to live the comfortably modest life he chooses.

From a CNN story about a traffic accident that injured Greenbaum and killed a motorcyclist:

Greenbaum needed a cane in that 2016 video above as he recuperated from the accident. Here’s how he looked and moved back in the 70s.

So once again I ask…how in the world does a different 76-year-old rocker named Mick Jagger do what he does?

Walk. Run. Bend. Stretch. Live.
