Well, the original Rascals reunited and performed together for the very first time in 40 years on Saturday night and Bruce Springsteen joined them on stage.

Felix Cavaliere, Eddie Brigati, Gene Cornish and Dino Danelli got back together for a benefit concert for the Kristen Ann Carr fund.

Kristen Carr was the daughter of Springsteen's co-manager Barbra Carr. The money went to fighting cancer.

More than 40 years ago The Rascals (or The Young Rascals as they were originally called) rolled out hits like 'Good Lovin', 'How Can I Be Sure', 'Groovin' and 'Ain't Gonna Eat Out My Heart Anymore'.

Saturday's show took place at Robert De Niro's Tribecca Grill in Manhattan. De Niro was there too.
