Art Carney, comic singer!
One of the best children's lps ever was "Doodle-Li-Boops and Rhinocephalopes," Columbia CL 2595. Not sure when this old 10-incher came out. Lost in the sands of time; it doesn't show up in Google.

Songs, by several lyricists, included:
The Dodo Bird in the Banyan Tree
Them
Flop, Mop, Cotton and Pete
Where Did the Chicken Lay the Eggie?
Mama, Mama, Mama
Santa and the Doodle-Li-Boop
