Leona Lewis, Yolanda Adams, Shirley Ceasar and Ce Ce Winans are the 'best' and few artists out there today that sing with emotion. It would not be flattering to hear someone get up there and just sing b/c that's not what Whitney did...picking artists for this should be a delicate process.....not about popularity and showmanship. Whitney loved melody and lyric. It wasn't just about getting up on stage and memorizing the words to a song....she told a story through her songs...her music spoke to her and because of that she was able to translate that to her audience----an artist that can do that will be the only way to truly 'honor' Whitney!
