Candide (operetta): Candide is an operetta with music composed by Leonard Bernstein, based on the 1759 novella of the same name by Voltaire.  The operetta was first performed in 1956 with a libretto by Lillian Hellman; but since 1974 it has been generally performed with a book by Hugh Wheeler which is more faithful to Voltaire's novel.  The primary lyricist was the poet Richard Wilbur.  Other contributors to the text were John Latouche, Dorothy Parker, Lillian Hellman, Stephen Sondheim, John Mauceri, John Wells, and Bernstein himself.  Maurice Peress and Hershy Kay contributed orchestrations.  Although unsuccessful at its premiere, "Candide" has now overcome the unenthusiastic reaction of early audiences and critics and achieved enormous popularity.  It is very popular among major music schools as a student show because of the quality of its music and the opportunities it offers to student singers.

A Sense of Wonder: A Sense of Wonder is the fifteenth studio album by Northern Irish singer-songwriter Van Morrison released in 1984.  On first release, original pressings had to be recalled when the W. B. Yeats estate refused to allow Morrison's musical version of the poem "Crazy Jane on God" to be included, as they believed his poems should only be set to classical music.  Morrison substituted "If You Only Knew" for the Yeats' recording.  (Later, perhaps due to Morrison's efforts, Yeats poems would be put to rock settings on a whole album).
