I've seen a half-dozen revivals of ''Merrily'' over the years, so I'm well aware of how the show and its score have changed.
My original query was: ''Did Tunick write new orchestrations for the current revival or are these orchestrations that were not previously Tony-eligible?''
According to Playbill.com, this 2024 nomination is primarily based on Tunick's work in 1994 and these orchestrations weren't previously Tony-eligible.
