(hennemusic) Sammy Hagar joined country superstar Kenny Chesney to perform his signature 1984 hit, "I Can't Drive 55", at Levi's Stadium in Santa Clara, CA on August 6 and video of the jam has been posted online.

"I couldn't believe hearing 50,000 people scream 55 at the top of their lungs!!," says Hagar. "Certainly one of the highlights of my year musically so far!! Always love hanging and playing with Kenny."

The longtime friends have joined each other on stage several times through the years, with Chesney a regular guest at Hagar's annual Birthday Bash series at his Cabo Wabo Cantina in Cabo San Lucas, Mexico. Watch the video here.
