One big highlight on Idol Gives Back was a duet by Fergie and Heart. They performed a lively but shorter-than-usual rendition of Heart’s “Barracuda”.The performance featured The Duchess doing two cartwheels onstage.

“‘Barracuda’ is usually five minutes long, so we were sweatin’ it with the arrangement, and so was Fergie,” Nancy Wilson said backstage. “We had two chances to get it right. The first two times we got it very wrong. We actually did it right when it mattered.”
