That Sammy Hagar isn't really a Hagar. He's Sammy Belcher. Scandal in the 1800's. It was a fun watch on Finding Your Roots. Ed O'Neal's genetic breakdown was 100% Irish. That was funny also. Never seen that before.
He actually was a pretty good defensive lineman in high school and got a scholly to college. But, it didn't work out. Also, at the time of the filming he had a 16 year old daughter named Clare.
