Former CATATONIA frontwoman Cerys Matthews has played a secret gig for inmates at a high security prison in her native Wales. The singer, who recently divorced her American husband and moved back to the U.K., stood on a makeshift stage as she performed in front of 80 prisoners. She jokes, "I thought about doing Jailhouse Rock but didn't want to rub it in. The prison was pretty intimidating but I had a fantastic time."
