I want to know the answer to the following question:
How many people were at the Queen + Paul Rodgers concert in 2008 in Kharkiv?
All the background I'm provided with is that "On 15 August 2006, Brian May confirmed through his website and fan club that Queen + Paul Rodgers would begin producing their first studio album beginning in October, to be recorded at a "secret location".". Is that enough to answer the question?
