I want to know the answer to the following question:
In 2008 what disease did Queen perform benefit concerts for?
All the background I'm provided with is that "Queen + Paul Rodgers performed at the Nelson Mandela 90th Birthday Tribute held in Hyde Park, London on 27 June 2008, to commemorate Mandela's ninetieth birthday, and again promote awareness of the HIV/AIDS pandemic.". Is that enough to answer the question?
Answer: yes
