Led Zeppelin did NOT play at the Tangerine Bowl in Orlando, Florida, on August 31, 1971. They played at the Orlando Sports Stadium, later known as the Eddie Graham Sports Complex. It was demolished in 1995. This was Led Zeppelin’s only concert appearance in Orlando.
The Tangerine Bowl later became the Citrus Bowl and as of 2023 is known as Camping World Stadium. Led Zeppelin never played there.

I saw them in 1970 at the Spectrum, in Philadelphia

I don't know if this is allowed, but here is a review... A crowd of 70,000 paid between $10-$12 apiece for the opportunity to see Led Zeppelin, arguably the world’s biggest rock band at the time, perform at the open-air Tampa Stadium. The gates had opened around noon, and, so far, there had been no major incidents. The enormous mass of fans eagerly anticipated the guitar wizardry of Jimmy Page, the wailing vocal of Robert Plant, and the inevitable Bonzo drum solo. The band took the stage at about 8:15. However, anyone that has lived in Tampa will tell you: rain is unavoidable in the summer months Eleven minutes after the show began, it started to rain. The band, fearing what might happen to their electrical equipment in the thunderstorm, left the stage. The storm passed shortly after it started, but Led Zeppelin did not return to the stage. When an announcement was made that the band would not be coming back, angry concert goers on the field stormed the stage. The police guarding the stage were not prepared for the onslaught of 4000 angry rock fans.Eventually, other officers were called in with tear gas to break up the mob. There are conflicting opinions about whether the use of such tactics was justifiable, or if the incident could truly be labeled a riot. In the end, thirty-five fans and nine police officers were treated for injuries and twenty arrests were made.

Fans were assured that there would be a “raincheck” concert, and that the incident would not affect future shows at Tampa Stadium. Both of these statements turned out to be false. Led Zeppelin never returned to Tampa, and there were no more concerts at Tampa Stadium

Actually the concert was one day, not 3 times... and it was a mess! So disappointing! An ominous rain cloud over head, So much rain. A lot of lightning and loud thunder! flooding the interior of the stadium. it was hard to get out of there pushing and shoving! It got violent, even some friends of ours were badly hear, on was stabbed in the neck. There was no reason for the violence.. I can't believe people were expecting the group to play during a bad storm like that!

I remember Led Zeppelin played in Mobile, Alabama in either 1973 or 74, don't see it listed here.
