As part of a fundraiser to help Broadway Cares/Equity Fights AIDS, Aaron Tveit showed up at the Disaster musical’s Disaster Relief event last night. As part of an ongoing series, artists are asked to perform onstage after the curtain call to raise money for BCEFA. Because Aaron’s former Catch Me If You Can co-star Kerry Butler is in Disaster, it’s no surprise that we got to see a reunion — and it was anything but disastrous. Together, they sang a beautiful duet – “Seven Wonders” – which was a staple song for their CMIYC characters, Frank and Brenda. Check out the video above.
