Appeared in one of the all-time monumental flops on Broadway, the 1982 revival of George M. Cohan's "Little Johnny Jones" (the show that James Cagney's Oscar-winning Cohan performs while singing "Yankee Doodle Dandy" in the eponymous 1942 film), which was pitifully old-fashioned and out-of-date, even in those early years of Reaganism. The show opened at the Alvin Theatre on March 21, 1982 after 29 previews and closed that same day for a total of one (1) performance. Only those shows that close without ever having officially opened (that is, during previews) have done worse.

Donny's first appearance was on TV's "The Andy Williams Show" (1962) on December 10, 1963, one day after his 6th birthday.
