"Let's Do It" was the standout hit in the 1928 Broadway show, "Paris." It's the first of what Porter called his "list songs," in this instance listing all the creatures that "do it." "At Long Last Love" is another list song, listing alternatives ("is it the good turtle soup, or merely the mock?") Despite, or because of, its openly sexual lyrics, "Let's Do It" is one of Porter's most popular songs. This key-of-G arrangement includes the intro/verse, which is composed almost entirely of cirle-of-fifths 6-2-5-1s or 3-6-2-5-1s. The Chorus has a standard AABA form, and notice all the "turnarounds": G, G#dim, Am D7. The extended ending resembles Billie Holiday's 1941 recording of the tune.
