3933 days after Adam's first performance of the song on American Idol, on February 10, 2020 QUEEN + Adam Lambert performed a live cover of the song at the concert in Dunedin, New Zealand as part of the "Bohemian Rhapsody" tour. The song remained on the setlist for the rest of the tour.
It is worth mentioning that Brian teased the audience in Prague's O2 arena on February 17, 2015 with a few bars of "Whole Lotta Love". Adam did not join in, so it appeared to be just a musical joke.
Whole Lotta Love -
From American Idol To QUEEN + Adam Lambert
On May 5, 2009 during the American Idol 8 Rock Week, Adam performed the Led Zeppelin song "Whole Lotta Love". That performance has importance not only because it was the first time a Led Zeppelin cover was approved for the AI stage (see the relevant Global First page for more), but also because it was later revealed that it caused Spike Edney to discuss Adam with Brian and Roger, arguably setting the wheels in motion for the QUEEN + Adam Lambert collaboration.
