Context: Vincente Minnelli (February 28, 1903 – July 25, 1986) was an American stage director and film director, famous for directing such classic movie musicals as "Meet Me in St. Louis", "Gigi", "The Band Wagon", and "An American in Paris".  In addition to having directed some of the most famous and well-remembered musicals of his time, Minnelli made many comedies and melodramas.  He was married to Judy Garland from 1945 until 1951; they were the parents of Liza Minnelli. Minnelli on Minnelli: Live at the Palace was a concert presented by Liza Minnelli at the Palace Theatre on Broadway from December 8, 1999 through January 2, 2000.  The show consisted of songs featured in films directed by her father, Vincente Minnelli (1903-1986). Come Saturday Morning is Liza Minnelli's second studio album for A&M Records.  Released on February 1, 1969 in the United States, it contains the title track, which is taken from the movie "The Sterile Cuckoo".  In 1970 it was nominated for an Academy Award for Best Original Song.  Minnelli herself won a nomination for her acting performance, the first of her two for Best Actress.  The rest of the compositions are the same mix of mainly then-current pop/rock and singer/songwriters songs with a couple of Broadway/Vaudevillian songs that made up the previous album.  In the UK it was released as "Introducing Liza Minnelli". Liza Minnelli is a self-titled studio album by Liza Minnelli.  Released on February 9, 1968 by A&M Records in the United States, it contains her interpretations of pop/rock and singer/songwriters' songs. American singer Liza Minnelli has released eleven studio albums — "Liza!  Liza! " (1964), "It Amazes Me" (1965), "There Is a Time" (1966), "Liza Minnelli" (1967), "Come Saturday Morning" (1968), "New Feelin'" (1970), "The Singer" (1973), "Tropical Nights" (1977), "Results" (1989), "Gently" (1996), and "Confessions" (2010).

A Matter of Time is a 1976 American-Italian musical fantasy film starring Liza Minnelli and Ingrid Bergman, directed by Vincente Minnelli.  The screenplay by John Gay is based on the novel "The Film of Memory" by Maurice Druon.  The fictional story is based loosely on the real life exploits of the infamous Italian eccentric, the Marchesa Casati, whom Druon knew during her declining years in London while he was stationed there during World War II.  The film marked the first screen appearance for Isabella Rossellini, the last for Charles Boyer, and it proved to be Vincente Minnelli's final project. Mario Bava (31 July 1914 – 27 April 1980) was an Italian director, screenwriter, special effects artist, and cinematographer from the "golden age" of Italian horror films.  His work kick-started the giallo film genre and the modern "slasher film".  His son Lamberto Bava later went on to become a noted horror film director in his own right. Liza with a "Z": A Concert for Television is a 1972 concert film, made for television and starring Liza Minnelli.  The film was produced by Fred Ebb and Bob Fosse.  As well as producing, Fosse also directed and choreographed the concert, and Ebb wrote and arranged the music with his song-writing partner John Kander.  All four had previously worked on the successful film adaptation of "Cabaret" earlier in the same year.  According to Minnelli, it was "the first filmed concert on television".  Singer sponsored the production, even though the producers did their best to keep any of the sponsors from seeing the rehearsals for fear of them pulling out due to Minnelli's short skirts. "Maybe This Time" is a song written by John Kander and Fred Ebb which was included in the 1972 film "Cabaret".  It is sung by the character Sally Bowles, played by Liza Minnelli in the film.  It had already been recorded and released twice, in similar arrangements, on Liza Minnelli's debut studio album "Liza!  Liza! ", in 1964, and on Minnelli's 1970 album "New Feelin'", but it turned into a traditional pop standard after its 1972 inclusion in "Cabaret". Liza!  Liza!  is Liza Minnelli's debut studio solo album, released in September 1964 by Capitol Records.  It contained her interpretations of twelve pop standards.  It was recorded in June 1964 at Capitol Records' New York studio at 151 West 46th Street.  It was re-released in 1988 by Capitol, in a retitled version ("Maybe This Time – Liza Minnelli sings the sensational hit from the film "Cabaret"") with the same track listing and the songs in the same order, but a different cover art.
