"As long as you can boogie, you ain't too old!"

Using Captain Beefheart's criterion, the classic rockers who performed on the Grammy Awards telecast this week (2/5) definitely "ain't too old!"

According to a poll by the Grammy folks, more than half of the people who watched the awards were there because of the music. It wasn't an accident that the artists whose performances opened, closed, and populated the middle of the awards show were classic rockers.

Here's a look at the baby boomer rock fest at the 54th Grammys.
