Since Smile was never, in any shape or form, "presented" as a completed work prior to Brian doing just that, the title is perfectly fine.
We're getting very picky here. 8 years after the fact, this topic seems redundant.
Or to get even less specific, are there similar issues whenever a stage production, television show, film, etc. is prefaced by the credit "Presented by General Motors!" or "Producer X proudly presents..."? In those cases the credit was bought and paid for and had less to do with the person actually creating it as it did with a corporate sponsor or financial backer ponying up the funding for the show. At least Brian did, in fact, *create* the work he's presenting.
Is there an avatar where the cartoon yellow face is scratching his head in disbelief?
