I don't know if I'm the only one who has noticed this, but I'm convinced that Roger put a picture of Freddie in this album (Happiness). If you look at the picture in Roger's studio, you see a figure/s in a chair at either a keyboard or a mixing board. To me, it is clearly a picture of Roger leaning forward, super-imposed with a picture of Freddie leaning forward a bit, but slightly behind Roger - signifying that Freddie was there 'with him' as he was recording. Freddie was obviously front and center in Roger's thoughts when he made this record, and 'Old Friends' is probably the one Roger song I'd put on if I had one choice. Has anyone else seen this? Take a look and see what you think.
Here's a scanned copy of the photo I think you're talking about. Personally I'm undecided, I see Roger's face and there does appear to be a dark haired head as the other blurred image. Hard to say... Interesting find.
