14. The Eurythmics (1984): Annie Lennox Inspires Lady Gaga
Twenty-seven years before Lady Gaga came to the MTV Video Music Awards dressed as her Ralph Macchio-esque character Jo Calderone, Annie Lennox pulled a very similar move during the Eurythmics' performance of "Sweet Dreams" at the 1984 Grammys. (The similarities between the two characters are pretty striking.) The Eurythmics split up years ago, but are going to reunite this year to honor the Beatles.
