Creedence yes, Ike & Tina no.
I had some trouble getting onto the Rock Hall Web site earlier, but I wanted to check whether tonight's contestants stuck to the hall's "500 songs that shaped rock and roll" list that the hall thought was the basis of tonight's song selection. Now that I've checked, the answer is basically yes, although there were some nuanced differences.
David Archuleta: Both Ben E. King's "Stand By Me" and Elvis's "Love Me Tender" are on the list.
Jason Castro: "I Shot the Sheriff" is on the list, credited to the Wailers (with a note that the Wailers included Bob Marley). "Mr. Tambourine Man" is on the list, but for the Byrds' version, not Bob Dylan's original.
David Cook: Both Duran Duran's "Hungry Like the Wolf" and the Who's "Baba O'Riley" are on the list.
Syesha Mercado: Sam Cooke's "A Change Is Gonna Come" is on the list. "Proud Mary" is on the list in the Creedence Clearwater Revival version, not the Ike & Tina version she drew on.
I'm not saying there was any more rule-bending here than in any given category on "Idol."
But, as you can see from the complete list, there were some real opportunities that the contestants didn't take on. I've already said that I don't think the show licensed the entire catalog. Still, the possibilities for great performances were considerable, and tonight's so-so results are yet another reason to lament the state of the show this season.
