Well, this is a dream team if we've ever seen one!!
Cyndi Lauper and Adam Lambert took to the stage together for a rendition of Mad World by Tears for Fears.
The once-in-a-lifetime moment took place during the Cyndi Lauper and Friends: Home for the Holidays at New York's Beacon Theater to benefit the Time After Time singer's True Colors Fund to benefit LGBT youth.
We love a charitable cause, especially when it brings together such a cool group of people, including Sarah McLachlan, St. Vincent, Jason Mraz, Whoopi Goldberg, and Rosie O'Donnell.
You weren't in New York to enjoy the festivities either?! Enjoy the MADNESS (above) !!!!
