His first professional appearance was on the Lithuanian Furniture Company Radio Hour (Station WHAT) on which he rendered Irving Berlin’s “So Help Me.” Wrote Stephen Holden in The New York Times: “While Noël Coward is no longer around to set the standards for a certain kind of sophisticated songwriting sensibility, Mr. Wallowitch nimbly carries the torch.” He displays his predilection for Coward-like wit and satire on such songs as “Cosmetic Surgery”, in which he sums up the surgical predilections of friends who are “getting younger than ever” with such dexterity.
In a matter of weeks With the modern techniques For improving physiques They have altered their beaks And they've lifted their cheeks And now everyone speaks In society's cliques Of the changes that science has wrought Of the changes that money has bought!
Wallowitch’s compositions have also been recorded by Shirley Horn, Tony Bennett, Berri Blair, John Dubois, Marlene VerPlanck, Lynn Lobban, and many others.
Among the many fine performers who sing his songs are Lynn Lobban, Alice Levine, Eric Comstock, Yvonne Sherwell, Sue Gandy, Joanne Beretta and Michael Belliveau.
Henry and Bobbie Shaffner, veteran members of ASCAP, wrote the lyrics and set them to the tune of the old Groucho Marx song, “Lydia, the Tattooed Lady”.
During 1989, comedian Chris Elliott would parody Wallowitch on the "Late Night with David Letterman" show portraying the musical character Johnny Graham, who took requests via telephone.
