There are two shows that I wanted desperately to leave at intermission, but ended up staying, thinking something good might happen in Act Two. I was wrong both times. The runner-up for worst musical I have ever seen was Anthony Newley's 1962 English import STOP THE WORLD--I WANT TO GET OFF, although it had one song that became a big hit, and rightfully so: "What Kind of Fool Am I". I just found the acting, book and staging so annoying. I did leave during curtain calls and ran out to get a drink. The absolute worst musical I have ever seen, without one trace of redeeming value, was NICK & NORA (1991) with of all people Arthur Laurents as librettist and director. It was a murder mystery where no one cared who did it. My friends left at intermission, but I stupidly stayed to the very bitter end. It's miserable score was written by Charles Strouse and Richard Maltby, Jr. Despite some big name cast members(Barry Bostwick, Joanna Gleason, Christine Baranski, and Debra Munk), the acting was terrible. It closed quickly, unlike STOP THE WORLD which had a respectable run for 1962, 556 performances.
