what about Never?
sure heīs done more covers, on top of my head I'm sure he did When A Man Loves A Woman once during the 9 tour, somewhere in the US... he also used to do Princeīs Kiss (there is a medley with Face on YT)... thereīs also this traditional song called Black is the Colour, he did in Australia once in the 9 tour, thereīs a low quality video on YT
in the Juniper (released by Damien) section, you can add Cross Eyed Bear and Me, My Yoke & I... Needles, too? plus The Professor and Woman like a Man are not unreleased...
in regards to collaborations, isnīt One just Damo solo (no Bono), at least on the Q CD that I got...
