The entire album for the Walt Disney World band is located
here on iTunes. You can purchase the whole album for $9.99 or just the first and second songs for 99 cents each. They're pretty much what you're looking for.
Versions from the Disneyland Band(I'm almost skeptical the tracks are different heh, but same thing) have been available for the Mickey Mouse Club march on various Official Albums they do each year. One copy was on the 1996 and 1997 cds that many people ended up getting for example.
