Come On! Feel the Illinoise! (Part 1: The World's Columbian Exposition; Part 2: Carl Sandburg Visits Me in a Dream)

Sorry if I offend you Jsh17 by not making a comment on the meaning of this song; but about 2:20 into the song there is a really cool trumpet bit which reminds me so much of an old(ish) song and I was wondering if anyone else can pick it, cause I can't. It's been bugging me for ages :p
