John, they just came out yesterday on DVD. It's a 2-disc set with all the songs, including a long-lost weather one, a new one about elections, and other extras. There's an extensive thread about it over in the software forum.
My local Wal-Mart has a pricing manager who might be a little eyesore.
They have a thing where for some of the titles they post their written in-store price and then under it, have a clipping of a competitor's ad. Sort of a "We have the best price period!" sale.
Get this...
My Wal-Mart has Schoolhouse Rock for $11.97, beating out Target's $12.99 price.
The kicker?
Its $12.99 for the VHS release not the DVD! The DVD is listed as "Hot Price" in Target's ad. You can even see it in the clipping.
