After rocking out with Bon Jovi last week, this week, it's time to dance. But who is going to tackle (the strangely appropriate) "Stayin' Alive" on Tuesday's Idol? That's the $500,000 question as the remaining four contestants gear up for Bee Gees night. Guest mentor Barry Gibb will supply the dancefloor-ready tunes (and hopefully tips at how to squeak the most out of their falsetto range) as he mentors the hopefuls and then performs on Wednesday's show. Known for their fleet of disco-friendly hits like "Jive Talkin," "How Deep Is Your Love" and, of course, their Saturday Night Fever smash, the Bee Gees' back catalog should prove a welcome challenge to the talented foursome. Plus, apart from vocal tips, expect the hirsute Gibb to supply style and performance advice in spades – just no leisure suits, please.
