The only pop use of the word sacroiliac I knew before last week was the Blondie song "Rapture." Now I can add the film Mr. Blandings Builds His Dream House and the Bing Crosby - Andrews Sisters number, "South America, Take It Away." It makes me to admire Deborah Harry that much more.

UPDATE: Ben Friedlander mentions Grandmaster Flash's "The Message," from 1982, the year after "Rapture." Herb Levy says there's a dance song from the 50s or 60s; the search wizard returns Parliament's "Chocolate City," a song by Black Box (what that?) called "Ride on Time," and Frank Sinatra's "The Hucklebuck," which, SECOND UPDATE, John tells me, is a cover of a song music (not lyrics) by Charlie Parker.
