Glazer, with Dottie Evans, recorded three children's records in 1959 and 1960 that were part of a six-album set known as
Ballads for the Age of Science. They contained songs intended to explain science concepts for young children, all of which were written by
Hy Zaret (lyrics) and Lou Singer (music). One of these albums,
Space Songs, included the song "
Why Does the Sun Shine?" which was later covered by
They Might Be Giants. His greatest commercial success came with his original 1963 recording of the song parody "
On Top of Spaghetti" to the tune of "
On Top of Old Smoky", which he recorded for
Kapp Records with the Do-Re-Mi Children's Chorus. The song was later included on an
LP record that also included such numbers as one of the first cover versions of "
Puff, the Magic Dragon", as well as "
Battle Hymn of the Children" and other children's songs. Glazer became ambivalent towards his creation, saying that "I'm standing in line before the Pearly Gates in the musicians' line, in which I stand last. When I'm asked what have I done in music and I say I wrote 'On Top of Spaghetti', I'm told, "Sorry, buster, you can't enter." ==Other hits==
