Question: It was this day in Rock History in 1974, these guys attended an Elvis Presley show at the Los Angeles Forum in California. Who was it?

Answer: It was Led Zeppelin! After a shaky start to the show, Elvis stopped the band and jokingly said: ‘Wait a minute, if we can start together fellas, because we’ve got Led Zeppelin out there, let’s try to look like we know what we’re doing.’ All four members of Zeppelin met with Elvis after the show, spending over 2 hours backstage. Elvis asked for all the group’s autographs for his daughter Lisa Marie.
