The animated Laurel & Hardy would make another appearance in Scooby-Doo Meets
Laurel and Hardy (IMDB lists Daws Butler as the voice of Laurel & Hardy, while Wikipedia lists Larry Harmon & Jim MacGeorge), where they join the Mystery Inc. team at a ski resort.
The Three Stooges' animated form made further animated appearances in 2
New Scooby-Doo Movies: Ghastly Ghost Town, and The Ghost of the Red Baron.
Unfortunately, neither Moe, Larry, nor Curly Joe DeRita voiced their animated counterparts, because Larry Fine had suffered a paralyzing stroke in 1970, which resulted in Larry's retirement, with Paul Winchell as Moe, Joe Baker as Larry, and Frank Welker as Curly (all uncredited) in the Ghastly Ghost Town and Ghost of the Red Baron Scooby-Doo movies.
Winchell, Baker, and Welker would later reprise their animated versions of Moe, Larry, and Curly in The Robonic Stooges, which originally started out as a short subject on The Skatebirds until its cancellation, but is now seen as an occasional stand-alone short subject on CN Boomerang to fill the non-commercial gaps between programs.

Joe Besser, who was hired to finish out the Three Stooges' contract with Columbia Pictures after Shemp died of a heart attack in 1955, would find work in animation as a voice actor, lending his voice to such characters as Babu from the animated Jeannie (September 1973 - August 1975), and Scare Bear from Yogi's Space Race and Galaxy Goof-Ups.
Harold Peary, best known as The Great Gildersleeve from 1941-1950, would lend his voice to dude ranch proprietor Fenwick Fuddy in Buford and the Galloping Ghost, and occasional appearances on Yogi's Space Race.
