If the idea of ’60s rockers the Rascals reuniting this past weekend for just the second time in 40 years wasn’t enough, rock icon Bruce Springsteen made it all the more memorable when he hopped onstage for the band’s encore, a rousing rendition of the group’s timeless nugget ‘Good Lovin’.’ As WMMR reports, it all went down in New York on Saturday night at Robert DeNiro’s Tribeca Grill in the name of charity, with proceeds from the reunion of Felix Cavaliere, Eddie Brigati, Gene Cornish and Dino Danelli going to benefit the Kristen Ann Carr fund.

The cancer charity is named for the daughter of Springsteen’s co-manager Barbara Carr and Boss biographer Dave Marsh who died of sarcoma in 1993 at the age of 22. Recognizing the E Street Band’s guitarist Steven Van Zandt and his wife Maureen, the annual Kristin Ann Carr Fund’s “A Night to Remember” also found Little Steven joining in on the encore, which can be seen here. Van Zandt — who called the Rascals his favorite band when he inducted them into the Rock and Roll Hall of Fame in 1997 — has known the various members of the group for 30 years and has tried to reunite them.

“We first met around 1980 to discuss reuniting the band and have tried every five years or so,” Van Zandt told Backstreets. “Maureen suggested we give it one more shot and sure enough it took Kristen’s amazing spirit to finally get it done.”

Cornish also told the Springsteen fan publication, “I speak on behalf of the band when I say all the money offers in the world could not entice the Rascals to reunite, but four phone calls from Stevie and without hesitation we enthusiastically and immediately agreed to both support this wonderful cause and honor Stevie and Maureen.”
