Oh Yeah. ELP at the Anaheim Convention Center 1974. I found out later that was where the live album was recorded. Welcome Back My Friends. I met Keith Emerson there a few years back at the NAMM show and told him that's where it was recorded. He didn't know either. It's not stated on the album. I found out when I was on facebook with ELP's musicologist. But a great show for 3 dudes.
