September 7th, 1968, four guys who go by the last names of Bonham, Jones, Plant and Page came on the music scene as Led Zeppelin...sort of.  On that night, they were about to perform a gig in Denmark at the Teen Club.

They were introduced though as the New Yardbirds. During the Scandinavian tour, they were allowed to use the New Yardbirds name. It was after that tour, the band had to change their name, and Led Zeppelin was born. Reports of the show were propositive with over a thousand youngsters attending.

It was about a month later that they recorded their first album as Led Zeppelin, and the rest is history.

For this week's Classic Rock Pick, take a look back at Led Zeppelin performing Communication Breakdown and Dazed and Confused from a show in 1969, including a rehearsal before the show.
