In 1980 Led Zeppelin announced their first U.S. tours in years to support their current album at that time, In Through the Out Door. Four November dates were announced for Chicago. On September 25th, 1980, the very same day that thousands of fans placed their ticket orders, Zeppelin drummer, John Bonham, had tragically passed away. The Led Zeppelin era was over and the concerts never happened. For six years the unused concert tickets sat in the now demolished Chicago Stadium until Metro Pulse, Inc. acquired the entire quantity. The tickets were purchased and held by Metro Pulse until 1994 when a quantity were sold to collectors when the Chicago Stadium was torn down. Click here to see the ticket ad. Now the remaining tickets are available to Led Zeppelin fans everywhere. Metro Pulse is issuing two different collector sets each with certificates of authenticity in conjunction with the 20th anniversary of the death of John Bonham and the date of the ticket release. These rare items are a tribute to the legend of Led Zeppelin and the frenzy they caused every time they came to the old Chicago Stadium.
