Zorba is a musical adapted from the 1952 novel Zorba the Greek (Nikos Kazantzakis). The subsequent film in 1964 was also titled Zorba the Greek, but the Broadway musical was simply called Zorba. It focuses on the friendship that evolves between Zorba and Nikos, a young American who has inherited an abandoned mine on the isle of Crete, and their romantic relationships with a local widow and a French woman, respectively.
The musical premiered on Broadway in 1968, directed by Harold Prince. The original production ran for 305 performances, but a 1983 Broadway revival ran for 362 performances with a cast starring Anthony Quinn.
While there were no clips available for the Broadway show, this is from the film Zorba the Greek, with Anthony Quinn and Alan Bates in the roles of Zorba and Nikos.
