The reunited Eurythmics unveiled their new single, "Seventeen Again," and played a seven-song acoustic set at New York's Kit Kat Club on Thursday night (Sept. 30). Singer Annie Lennox, 44, and guitarist Dave Stewart, 47, dressed in camouflage outfits, played versions of "Sweet Dreams (Are Made of This)" and "Here Comes the Rain Again" as well as Lennox's "Why" during the party, celebrating the Oct. 19 release of Peace, the synth-pop duo's first album since We Two Are One (1989). The single is an acoustic ballad that quotes the Eurythmics' 1983 hit "Sweet Dreams (Are Made of This)," with Lennox singing, "Sweet dreams are made of this/ Who'd have a mind to disagree/ And travel the world and the seven seas/ Everybody is looking for something" as the song ends. Rapper Wyclef Jean and actor Kevin Spacey attended the party.
