“The Eggplant That Ate Chicago”  is a song about alien invasion by Dr. West’s Medicine Show and Junk Band.  Although often listed as a “one hit wonder”, the song did not actually reach the top 40; and the author of this song, Norman Greenbaum, would later write and perform “Spirit in the Sky” to greater chart success.  It was re released on Dr. Demento Presents: The Greatest Novelty Records of All Time, Volume III: The 1960’s (1985).  (More from Wikipedia)
