Bruce Springsteen Makes Surprise Appearance At Jam Session

The Boss gave a surprise performance Friday at an event at the Asbury Park Music and Film Festival in New Jersey.

Bruce Springsteen joined the Upstage All-Stars jam session on stage at the Paramount Theatre to mark the new documentary Just Before the Dawn.

The film looks at the short-lived music venue that was a breeding ground for many acts, including Springsteen.

The Boss did lead vocals on a cover of Little Richard’s “Lucille,” and played guitar on Muddy Waters song “Got My Mojo Workin’"
