I say we shouldn't be so quick to write off people who claim to have seen different versions of the movies. Knowing now how much George Lucas tinkers with things even after the release (this happened with Episode 1 and 2, too- did you know there wound up being 3 different versions of Episode 1 before it ever even hit VHS?), I wouldn't be surprised if one version was playing in Utah, a different version was playing in Michigan, etc. etc.

I have heard so many people come forward having seen the Biggs scene earlier in '77 that I think we ought to take a closer look at it.
