Mariah Carey may bring in the numbers to music retailers, but the superstar didn't do much for American Idol -- beyond coaching Jason Castro to a decent performance. Last week's performance show, featuring her coaching and her songs, was the lowest-rated Tuesday Idol in five years among TV's most desired demographic, adults ages 18 to 49, according to Neilsen. The subsequent results show, in which Mariah performed her banal new single Bye Bye, similarly did disappointing business, the worst Wednesday showing for that age range since Season 1 in 2002.
This Tuesday, Broadway songwriter Andrew Lloyd Webber coaches. Next week Neil Diamond coaches and on the results show he'll sing his strikingly good new single, Pretty Amazing Grace.
