I wouldn't be surprised if Jermaine being made fun of in private from Jackie, Tito, Marlon and Randy about his cover of Blame It On The Boogie. Because not only is Jermaine covering Michael's vocals on this song, his also covering Jackie, Tito, Marlon and Randy's backing vocals on the song. What next, Jermaine covering Show You The Way To Go or Can You Feel It, maybe even Billie Jean or Man In The Mirror.
Jermaine is a great vocalist compared and has the voice of a superstar (though not the stage presence of one), but when covering a song sung by Michael, Jermaine just sounds flat. And this combined with the fact Jermaine doesn't have a strong enough stage presence to cut it as a solo artist, just makes him look talentless. Jermaine should stick to singing his own songs, and not cover any of Michael's music in the recording studio. Because Michael's vocals can't be equaled even if your a sibling with exactly the same genes as Michael.
