I want to know the answer to the following question:
Which band was he largest benefit concert in history about?
All the background I'm provided with is that "Performers, including Def Leppard, Robert Plant, Guns N' Roses, Elton John, David Bowie, George Michael, Annie Lennox, Seal, Extreme, and Metallica performed various Queen songs along with the three remaining Queen members (and Spike Edney.)". Is that enough to answer the question?
