John Lennon Revolution sneakers and the adidas SL72

We've covered a decent amount of bootleg sneakers on this blog but I am wondering if there are any adidas aficionados that knows the story behind these John Lennon 'Revolution' sneakers? They look like re-branded Adidas SL 72's. This "collab" came out around 2010ish (I think) and is a little weird because John Lennon wore a lot of Stan Smith sneakers and I haven't found one photo of him in SL 72s. These were for sale over at Amazon but are sold out. Bummer.
