Behind-the-scenes footage from MÖTLEY CRÜE's appearance on the season finale of “American Idol” can be seen below.

A week and a half ago, MÖTLEY CRÜE was joined by country-pop superstar Carrie Underwood for a two-song performance featuring the band’s hit songs “Home Sweet Home” and “Kickstart My Heart.” The three-hour episode aired on May 11 on ABC and streamed the next day on Disney+ and Hulu.

The performance marked a nostalgic return to one of MÖTLEY CRÜE's most iconic ballads, with Underwood famously covering their song during her own time on the show in 2005.

She went on to sell seven million copies of her first album — the most successful CD to date from an “Idol” alum.

The episode featured a star-studded lineup including SHINEDOWN, Clay Aiken, Jason Mraz, Nelly, EN VOGUE, Tori Kelly, BLUES TRAVELER and GIN BLOSSOMS.

Lionel Richie, original “Idol” season 4 winner Underwood; and Luke Bryan judged the contestants in the three-hour episode.
