"Wind Up" is the final track on Jethro Tull's 1971 album, 'Aqualung." The "All Music Guide to Rock" specifically refers to "Wind Up"and its examination of religion and God as separate entities when it notes that the album "probably got lots of teenagers wrestling with these ideas for the first time in their lives." The book goes on to call Aqualung "one of the most cerebral albums ever to reach millions of rock listeners."
