The Grammy Award nominations were announced yesterday, and the Best Musical Show Album category was almost entirely made up of Broadway musicals. The nominated show recordings were: Ain't Misbehavin' (30th anniversary cast recording featuring American Idol's Ruben Studdard and Frenchie Davis), Hair (Broadway revival cast album), 9 To 5 The Musical (featuring a score by country music superstar Dolly Parton), Shrek The Musical (Original Broadway cast recording), and West Side Story (new Broadway revival cast recording). If you want to hear what the fuss is about, three of the musicals - Hair, Shrek, and West Side Story - are still playing on Broadway. The winners of the Grammy for Best Show Album will be announced in January.
