Duets are perfect by design for the love song. We get to hear both sides of the love story. We do not have to imagine another person. You’re All I Need To Get By (1968), by Marvin Gaye and Tammi Terrell, is the most powerful duet that I have ever heard. It reminds us of how powerful love is and music can be. This song stirs up an energy inside of me that makes me want to jump up and down. When I am all alone, I love to turn this duet into a trio. The temptation is very hard to resist.
