An unusual request made by Bono is among the latest E-mail revelations to surface from Hillary Clinton’s private server.

According to People magazine, the U2 frontman asked a former Bill Clinton aide if it were possible “to do a linkup with the International Space Station on every show” during the band’s 360 Degrees tour. Hillary’s aide Huma Abedin and Clinton Foundation executive Doug Band both replied, “No clue.”

Though the hoped-for hookups never took place, U2 featured footage from astronauts aboard the space station during shows on the North American and European legs of the 360 Degrees tour.

Bono has long been close with the Clintons. He performed at the dedication of the Clinton Presidential Centre in Arkansas in 2004.
