Kantor and Wolfe reprise their 2013 Second Stage performances in Jason Robert Brown's romantic musical.
Reunions from the casts of Taxi and Who's The Boss? took place as Danza welcomed friends including Judith Light, Danny DeVito, Christopher Lloyd, and Marilu Henner.
Jeremy Jordan and Anna Kendrick are the newest Jamie and Cathy to be recorded for posterity.
The musical will be presented as a benefit for The Actors Fund.
The concert kicked off Brown's tenure as an artist-in-residence at the swanky venue.
The benefit concert will feature performances by Christopher Sieber, Betsy Wolfe, and more Broadway talent.
Original stars of The Last Five Years, Parade, and The Bridges of Madison County, and 13 will perform in concert with the Tony-winning songwriter.
The benefit performance will also feature Jeff Blumenkrantz, Jennifer Cody, and Don Darryl Rivera.
