A ceremony honoring James Hetfield's work with children in the Bay Area included a free-form jam that found the Metallica frontman onstage with some very lucky kids.

They got to join Hetfield for a performance of Metallica's classic 'Enter Sandman' as part of the Little Kids Rock charity's annual Rockin' the Bay Benefit, held on Nov. 9 at Facebook's headquarters in Menlo Park, Calif. Hetfield received the inaugural Livin' the Dream award, created in honor of Josef Desimone, the late Facebook executive chef who helped create the Rockin' the Bay event. You can watch the video of their performance above.

"We're presenting James with this special award as a way to not only recognize his support of Little Kids Rock over the years," said Little Kids Rock founder David Wish, "but also his role as an inspirational presence in a band that has revolutionized and defined a music genre."

Jeff Campitelli (a session drummer who's played with Joe Satriani) and Marcus Henderson (who's played on the Guitar Hero video-game series) were also on hand to recognize Hetfield. Previous guests at the Rockin' the Bay event have included Sammy Hagar and Matt Sorum from Guns N' Roses.

Little Kids Rock works to raise awareness and funds to revitalize music programs in school districts hit hardest by budget cuts. The program has funded music programming for more than 112,000 public school children in 12 states since its founding in 2002.
