It’s now official. Seattle’s Key Arena will be included in Cher’s “Dressed To Kill” 49 city North American Tour on June 28.  Cher’s contributions to music, television and film earned her the nickname “The Goddess of Pop”.  She is the only artist to date to have a number-one single on a Billboard chart in each of the past six decades, from I Got You Babe, and Gypsies, Tramps & Thieves, to Believe; Cher is known as the World’s Number One Pop Icon for good reason.
