Sales of Adam Lambert's Acoustic Live! EP skyrocketed after his return appearance on Fox's American Idol.

The American Idol season 8 runner-up returned to the show that helped launch his career last Thursday to perform a reworked version of Aftermath.

The 29-year-old Lambert earlier announced that he'll donate the proceeds from the song to The Trevor Project, the California-based non-profit that runs the nation's only 24-hour confidential suicide hotline for gay and questioning youth.

Aftermath appeared on Lambert's debut studio album For Your Entertainment, which he featured in his just-completed world tour Glam Nation.

According to USA Today, sales of Acoustic Live! skyrocketed after the performance, selling more than 3,000 units last week, returning the EP to The Billboard 200 chart.

In October, Lambert released a video for the It Gets Better campaign, in which he told troubled gay teens to stay strong and proud. The It Gets Better Project, a collection of videos urging troubled LGBT teens to hang in there, because life gets better, raises awareness and funds for The Trevor Project.
