vixmom, in answer to your Last Starfighter question last night - The "Family version" is about 60-65 minutes, while the "full-length version" (the one which is designated as suitable for middle school and older) is about 85-95 minutes.
"Zandozan!" which is Louis' big production number, in the Family version f the script has a lyric suitable for all ages.
"Spring Break" was also changed, and shortened, for what I refer to as some "PG-rated" subject matter in the full version.
