Sophie Tweed-Simmons sang the national anthem with her mother, Shannon Tweed, as Sophie's father Gene Simmons, co-founder of the legendary band KISS, accompanied her on guitar, on Saturday, December 13, 2008 at the L.A. Derby Dolls Banked Track All-Star Exhibition Roller Derby at 1910 Temple St. in Los Angeles, California.

Commented Gene: "Our 'Gene Simmons Family Jewels' [Gene's reality-TV show] TV crew went downtown L.A. to film a spectacular event — the Derby Dolls (the sport of roller derby) knocking heads and butts for one of our episodes. Nothing you will see on the episode of the roller derby event is either staged or fake in any way. They really get their butts handed to them. Head really get knocked around. The girls on roller skates are the real thing — hell on wheels. And Soph, Shannon and I had the distinct honor of singing the national anthem at the event, in front of a big, excited crowd."

Derby Dolls is the premiere all-female, banked-track, quad-skating rock 'n' roller derby league in the Southern California area. Athletic and alluring, the L.A. Derby Dolls strive to be the fastest, most fearless ladies in fishnets. Within the league there are four teams: The Fight Crew, The Sirens, The Tough Cookies, and the Varsity Brawlers. While their uniforms may be stylish and their names playful do not be fooled by appearances — the L.A. Derby Dolls only skate pure, unscripted, real roller derby.
