Nearly four years ago, shy only of a few weeks, Whitney Houston passed away. But she remains the 4th biggest selling female artist in history, the most awarded female act of all time (in 2009 Guinness World Records cited her thus)  and the voice in ‘The Bodyguard’--the soundtrack to the movie of the same name, in which she also starred. ‘The Bodyguard’ original soundtrack album, in 1992, stayed for 20 weeks as the top album on Billboard. The singers Poova and Dasha Logan (missing their third, Rozz) tell why this tribute and their personal connection to the diva.
