Oh, Yes! Wyoming!
So about a week or two back I mentioned the website with the Superman/Seinfeld teamup. One of the properties of a good website is that it keeps adding stuff, which means viewers will come back repeatedly.
In this case, the site has added the Good Morning, America interview with Superman and Jerry to promote the website, a photo album of the two together (watching a baseball game from the stadium light supports), and, most importantly, a sing-along from the Broadway musical "Oh, Yes, Wyoming!" which is featured in the movie-mercial.
I think the song has the potential to be the next "Badger, Badger, Badger". Its here.
