I just thought I'd add a few trivia tidbits to this page many of the performers pictured still work for WDW The Large emceee fellow in the Red suit has played many other roles He was one of the first to portray Mack in the pirate Tutorial, he's also a pirate in the "Rusty Cutlass" band
http://www.rustycutlass.net/ that perfoms in the Pirate and Princess Parties as well as at the MCMVP's as well. His "main gig" however is now on Main Street as Stretmosphere Fire Chief Smokey Miller at the Magic Kingdom, he also played councilman miller before that current role.
last December I had the good fortune to run into a Card Shark Streetmosphere character at Disneys MGM studios (or so it was named at the time), with his brown suit, Fedora hat, and New York accent it took me several minutes to realize..."oh my gosh it's professor Terrance" who was the slight of hand card shark/Magician who although also wearing red in the photos above is the smaller of the two fellows (and he has a watch chain accross his vest)
Only very recently did I learn that the third gentleman in these photos, the singing Cowboy here, also has a regualr Disney gig too, it had piqued my curiosity as to if perhaps he did when I saw photos of him with the Rusty Cutlass band, it turns out he appears in Camp Minnie Mickey as Gui-Tar-Dan as his main job, very cool.
There are others in these photos as well the ladies of the horseshoe and the piano men, I don't know what has happened to any of these folks, although the Sept 1998 piano man bears at least a passing resemblance to Caseys' corners' "piano man Mark", I don't necessarilly think it is him (for one thing, I've never seen glassses on Mark ). As for the ladies since thier makeup and wardrobe might be considerably different if any of them were for instance streetmosphere at the studios or Magic Kingdom, I might have more trouble reconizing them even if I had seen them. but would appreciate input from others on any of these ladies and gentleman if they happen to know more about them and most especially if they are still entertainers at WDW.
