A scene cut from the Fringe season finale is available as a "Ford exclusive." Which makes sense, considering it's mostly product placement for the Taurus. But don't be fooled - there are clues about Violet Sedan Chair here too.
It's not hard to guess why the scene was deleted - all those loving shots of the Ford Taurus's sweet handling and kickass entertainment system don't really have that much to do with the ongoing struggle between parallel universes. (Unless this sequence is meant to suggest that, in the alternate universe, people actually want to drive Fords.)
The most interesting part of the sequence is the continued reference to Violet Sedan Chair, the fictional band that apparently made only one album on our Earth but made three albums on the other Earth. First referenced in "The Northwest Passage", the band was also mentioned in a JJ Abrams-edited issue of Wired. There are also some mysterious YouTube videos about them and assorted other online detritus, so it probably all means something, but damned if I can figure it out.
After all, if it was just some random throwaway line, why not pick a real band that only made one album in our universe like, say, um, the Sex Pistols? If nothing else, Peter telling his alternate father that "Anarchy in the U.K." was the soundtrack of his childhood would have been worth the price of admission.
