Wait - so even American Graffiti isn't the theatrical cut (CG opening shot aside)?!
The DVD version is the 1978 theatrical re-release which included four additional minutes that Lucas originally had in the 1973 version, but which were edited out by the studio for the original release in 1973. I can't recall every scene off the top of my head, but one of them is Harrison Ford singing when he and Cindy Williams are driving around.
*edit*
Also, the 1978\DVD version is stereo.
