A bit of George Duke trivia,George used to be afraid to sing,he thought his voice was horrible,i watched an interview where he was talking about his time with The Mothers Of Invention where he said he fought Frank tooth & nail about singing,Frank & George finally agreed that at key points in songs all George had to do was to sing one word,then later on Frank convinced him to sing short back ground vocal tracks,before George knew it he was singing entire shows.
Durring this period George also learned to play the synthisizer & fell in love with it.
