Hey there,
I'm glad you enjoyed it. I'm hearing excellent things. The way our benefit concert was cast (mostly as a fun tool to attract more performers, and thus, more audience) was to have multiple leading players, so each of the Leading Player's songs was performed by a different star, culminating with Ben Vereen, who won a Tony for the role originally. We were thrilled to have Rosie be a part of it-she's truly an entertainer, and that's what the role requires at that point of the show in particular.
