Stop the presses - how did Pete Seeger get to be 90 years old?

I was watching The Shield (season 4, episode 3) and at the end of the episode is Ben's funeral with a bagpiper playing Amazing Grace which turns into a rock version with vocals. There are hundreds of YouTubes by different artists singing the dirge version but I really like the rock version.



I haven't found the rock version with vocals, but I came across this video of Pete Seeger singing it at his 90th birthday. He just can't be 90. :eek:





If you happen to know of a good rock version of Amazing Grace, please.



There are some good guitar versions, but I can't find the vocal one.
