D'Or sang for Martin Luther King III at a Middle East Peace Initiative (MEPI) Conference in the summer of 2007 in Tel Aviv. King was in tears as D'Or finished his rendition of "Summertime", and the crowd was on its feet cheering. King was so moved that he extended an invitation to D'Or to sing at the 2008 "Realize the Dream" celebration honoring King's birthday at the Covenant Avenue Baptist Church in Harlem, New York – the last church in New York City that Martin Luther King Jr., spoke at prior to his 1968 assassination. D'Or obliged with a performance of "Amazing Grace" before a crowd including former President Bill Clinton and Dr. King who was reduced to tears.
