The 20 richest musicians of all time – You’ll never guess the billionaires (+Pics)

5. Bono: $600 million
Paul Hewson is known as much for his global diplomacy and forays into venture capital asU2’s music. His investment in Facebook’s IPO—via his Elevation Partners private equity firm—didn’t make him a billionaire, but U2’s“360 Tour” grossed nearly $800 million between 2009 and 2011, making it the biggest tour ever. (2005-06’s “Vertigo” tour is fifth on that list.) Combine that with Bono’s many investments (including private equity stakes, a clothing line, and a five-star hotel), the fact that the band owns all the rights to its own music, and Bono’s Romney-esque tax-dodging investment schemes, and the numbers add up quickly.
