Bono (56), The Edge, Larry Mullen and Adam Clayton may be around for over four decades but they remain Ireland's wealthiest music act. The Dublin rockers, who shifted parts of their business to the Netherlands 11 years ago to reduce tax, made 52m in the 12 months through June, according to Forbes.
As the importance of record sales began to diminish, U2 became a touring machine. Another tour will follow this year to mark the 30th anniversary of The Joshua Tree, with 1.1m tickets sold worldwide in the first 24 hours of going on sale in January, meaning U2 could command up to 93m from the endeavour. The band's 360 tour from 2009 to 2011 was the highest-grossing tour of all time, with the band said to have made 660m out of it.
Outside of music, band members have diverse interests and investments including a stake in the Clarence Hotel, which recorded profits of more than 430,000 for 2015, and Dublin Dockland properties.
The Dubliners also own some smashing houses, from Killiney Hill to valuable beach-front castles in Eze and Beaulieu on the Cote D'Azur. Bono is a partner in $1.9bn US tech venture capital firm Elevation, which is sitting on stratospheric profits from a 2.3pc
stake in Facebook bought in 2009, and is now winding down.
