FIRST OFF . . .

“A Chorus Line” high-kicked its way past performance number 5,000 Saturday night, and the final curtain is not in sight for the longest running show in Broadway history. Some 16.7 million people have seen the show at the Shubert Theater in New York, where it opened on July 25, 1975. The gross for the Broadway company alone reached more than $119.4 million last May, with a profit of some $17.4 million. Major touring companies have added another $13 million in profits. The musical became Broadway’s longest running show on Sept. 29, 1983, with its 3,388th performance.
