It was only a matter of time before Bono weighed in with a tribute to David Bowie - but instead of a simple tweet or message on U2's website, he has written a eulogy in Rolling Stone magazine.
The U2 frontman, writing from Myanmar, called Bowie 'my idea of a rock star'.
"The first time I saw him perform was on Top of the Pops in 1972, singing "Starman," he recalled. "He was so vivid. So luminous. So fluorescent. We had one of the first color TVs on our street, and David Bowie was the reason to have a color TV."
He also recalled the period that U2 recorded Achtung Baby in Berlin's Hansa Studios, where Bowie visited them, saying " We had a playful sort of banter — he would really go there in conversations, and we would even occasionally hurt each other's feelings. He took his daughter to a matinee to see Spider-Man: Turn Off the Dark, and he sent me the reasons he didn't like it. And everything he said was really helpful, because it was in the early days of the show."
