Bono has told how David Bowie did not like his Spider-Man musical and was critical of it.
The U2 frontman said he was not offended because his criticisms were helpful to the show.
Bono and The Edge wrote the music and lyrics for the 2011 musical which became the biggest flop in Broadway history.
Bowie died on January 10 following a secret battle with liver cancer.
"We had a playful sort of banter - he would really go there in conversations and we would even occasionally hurt each other's feelings," said Bono.
"He took his daughter to a matinee to see Spider-Man: Turn Off the Dark, and he sent me the reasons why he didn't much like it.
"Everything he said was really helpful, because it was in the early days of the show."
Bono also revealed that his daughter, Jordan (26), was a huge fan of the Starman singer.
"Over Christmas, my oldest daughter Jordan and I were listening to Blackstar a lot," he said.
"David met her when she was two. He called her Pixie and she's been a lifelong Bowie fan."
Bono (55) also reached out to Bowie on his 69th birthday, two days before he died.
"I sent him a picture of myself and Jordan toasting him on his birthday this year," he said.
"I sent him a long email, and I sent him a beautiful poem by Michael Leunig called Love and Fear - one line goes, 'There are only two feelings/love and fear'. I didn't hear back, but I was told he got it."
Speaking to Rolling Stone magazine for its upcoming Bowie tribute issue, Bono said the world was a much darker place without him.
"Right now, I'm in Myanmar, a little cut off from the reaction to David's passing," he said.
"But I can assure you that the sky is a lot darker here tonight without the Starman.
"He was so vivid. So luminous. So fluorescent."
