Gabriel Cohen covers a Broadway high-wire act: pit musicians who fill in for the regular performers, sometimes on 15 minutes’ notice.
… Jeff Schiller, another “Kinky Boots” sub, recalled, “I got a call half an hour into a show, when a regular was experiencing incredible kidney stone pain.” Luckily, Mr. Schiller, who goes by the nickname Houndog, lives near the theater district. He swapped in between numbers in the middle of Act One.
