This is what we found on Wikipedia regarding the Aspects of Love:

Aspects of Love is a musical with music and book by Andrew Lloyd Webber, and lyrics by Don Black and Charles Hart. It is based on the 1955 novel by David Garnett.

The piece focuses on the romantic entanglements of actress Rose Vibert, her admiring fan Alex Dillingham, his underage cousin Jenny, his uncle George, and George's mistress, sculptor Giulietta Trapani, over a period of 17 years. The "aspects" of the title refers to the many forms that love takes in the show: love between couples, both as romantic infatuation and as married people; children and their parents; and hints of same-sex attraction (Giulietta and Rose).

Most of the musical is sung, making the show sung-through with only minor amounts of dialogue.

Lloyd Webber was introduced to Aspects of Love in 1979, when he and Tim Rice were approached to write a few songs for a proposed film version. When nothing came of it, he suggested to Trevor Nunn that they collaborate on a stage adaptation. In 1983, they presented a cabaret of numbers they had written, but it was not until five years later that they tackled the project in earnest. The musical features the song "Love Changes Everything".

As with many of his shows, Lloyd Webber first presented Aspects of Love in a workshop presentation as part of his Sydmonton Festival (July 1988). The cast was led by Michael Ball as Alex, Susannah Fellows as Rose, Dinsdale Landen as George, Grania Renihan as Giulietta and Diana Morrison as Jenny.
