Hy Zaret And Lou Singer
Hy Zaret (lyrics) and Lou Singer (music) wrote "A Shooting Star Is Not A Star" and "Why Does The Sun Shine?". Both songs were released on Space Songs (Motivation Records (Argosy) MR 0312; 1959), on which they're performed by Tom Glazer and Dottie Evans. Zaret was best known for writing the words to Unchained Melody.
Recently, Argosy Music restored Zaret and Singer's work in digital high-fidelity. Information on Space Songs, as well as a free PDF songbook and links to purchase the album and its five science-themed counterparts can be found here.
