Gene Simmons sang the National Anthem as part of an a cappella group of USO members, and ended by flashing the ASL sign for 'I love you'. Rolling Stone, however, saw devil horns.
And maybe he was trying to throw up the horns... but if so, he did it wrong. BUT, I've read that he actually does this a lot and it is meant to be ASL. KISS fans, what say you?
