The event raised money for the Light of Day Foundation — which raises awareness of Parkinson’s disease — and celebrated the birthday of music industry veteran Bob Benjamin, who’s battling the disease.

Bruce had not been officially announced to the lineup for the Paramount Theater benefit, but word of his appearance leaked when he showed up to a soundcheck.

According to Billboard, Bruce joined Willie Nile for a rendition of Nile’s “One Guitar.” He also teamed up with Asbury Jukes frontman “Southside” Johnny Lyon on a number of songs, including Jackie Wilson’s “(Your Love Keeps Lifting Me) Higher and Higher” and the Joe Cocker version of The Box Tops’ “The Letter.”

Springsteen songs such as “Darkness on the Edge of Town” and “Janey, Don’t You Lose Heart,” as well as the Bruce-penned “Because the Night,” were also part of the night’s festivities.
