"Steamboat"
The backing vocals sing the lines "Don't worry, Mr. Fulton / We'll get your steamboat rollin'," which refers to Robert Fulton, the inventor of the steamboat.
"Funky Pretty"
One of the lines is "A book of verse, a jug of wine," which comes from The Rubáiyát of Omar Khayyám. I got this for Christmas last year, but I haven't read it yet; I actually recognized the reference because this same line is quoted (misquoted, actually) in an episode of The Monkees ("The Wild Monkees" S2E10) and the DVD trivia points out the allusion. In Edward FitzGerald's translation, the relevant section (XI) is:
Here with a Loaf of Bread beneath the Bough,
A Flask of Wine, a Book of Verse - and Thou
Beside me singing in the Wilderness -
And Wilderness is Paradise enow.
