What did Broadway theatres do to commemorate the death of Fred Ebb?

Answer 1

In addition to dimming the lights in tribute, I found these items:

"In honour of the recent passing of FLORA's lyricist Fred Ebb, the Drama Centre is proud to present Kander and Ebb's first Broadway musical. The show was described by one reviewer at its recent Scottish premiere as "as masterful a piece of musical theatre as their later work." Director Laura MacDonald points out, "It was Kander and Ebb's work on Flora that got them hired to write Cabaret the following year."

"...the Broadway Cabaret Festival at Town Hall would kick off with a stirring tribute to the dynamic team of John Kander and Fred Ebb that became one of the more emotional and intense events ever held in that great hall. Broadway’s best and brightest turned out to honor the great duo, and, combined with creator and host Scott Siegel's witty narration, gave some classic songs new and exciting life"

There is also a tribute CD
