Bono hanging around

"As we were thinking of how to commemorate the 20th anniversary, we were looking at outtakes and different versions of songs that we recorded at the time. Some of the obscure, rare and maybe even unreleased things. So we put together a collection of tracks that people wouldn't be able to access on CD or vinyl." - The Edge on the 20th anniversary edition of All That You Can't Leave Behind, 2020
