Veteran photographer Steve Schapiro reveals the tale behind one of his most extraordinary images of David Bowie imitating his hero Buster Keaton

I wouldn't really describe myself as a fan of David Bowie, or his music for that matter, but I do find this photo to be authentically touching. An homage to a truly talented performer that he appreciated.
This compared to the sad use of David's photo to schlock a single that can only be seen as self-promoting. An affront to the memory of the man that at least at one point Moz purportedly idolized.
Many posters here spend an equal amount of effort and energy denigrating those with negative opinions about Morrissey as they do white washing all of the BS he and his needy nephew propagate. Please try and be open-minded enough to see this when commenting on those with dissenting views even if you oppose the manner in which they are given.
