If You Love  the song LAURA, you should love Theme From The Bad and The Beautiful, both by David Raksin. Jenness & Velsey said of Raksin that his songs have " Excellent, far-ranging voice lines combined with eztraordinarily lush chords with melodies that are very broad and expressive,"  "Love is for the Very Young" is the title of lyrics provided by Dory Previn based on the Raksin theme. Michael Feinstein recorded her version but am unable to retrieve it at present.
Raksin, himself, conducts a symphonic version of this magnificent and challenging melody.
