The answer, of course, is Neil Diamond!!  In a bar, auditorium, lounge, stadium or any gathering, as soon as he sings the words "Sweet Caroline...", the entire room will join together to sing "Bomp, bomp, bomp!".  A few seconds later you'll hear "So good, so good, so good" and then one more "Bomp, bomp, bomp."  I've done it a few times doing Karaoke and the response is automatic.  Senior citizens or youngsters, rich or poor, north or south, we all join in.  Thanks Neil!!!
