Characters voiced by two people at once
On another forum that won't let me on, this topic was on (some of its members are here and are my friends here..) but here are some (CLASSIC,"thru-1960s" era only) examkples.
Dunna if this counts but
the "Boarderss" (FLINSTONES),with the two young-adult "beatniks," famously had WIlma talking with Bea Benadaret's Betty voice...
A HICK,A SLICK,AND A CHICK (Warner Bros.,1947), had Mel Blanc as the Slick (Blackie), Bea Benadaret as The Chick (Daisy) AND Stan Freberg AND Mel Blanc (during drunk scenes)--during drunk scenes, as the Hick (Elmo), then not that but a Mel Blanc-voicerd cat later does a Durante voice,somthing I THNK Mel could never duplicate.
WIDEO WABBIT (WB,1956): THe normally Blanc-voiced Bugs imitating celebrities with Daws Butler's voice (though Mel does BUGS as Liberace)
SWORD IN THE STONE (Disney, 1963) Ricky Sorenson, a child actor of the day, played "Wart", the star character and the future King Arthur but the director (Woolie Reither's) two kids, Robert and Richard (just like the songwriter Shermans,[MARY POPPINS] who animated debut was this very knight-FLICK] provided the voice of "Young Kinf Arthur" once Ricky Sorenson's deeped as Rick aged. Also, raido's "Vera Vage"---Barbara Jo Allen----played the minor character, a Scullery Maid in the castle..-------buttt----(he said "butt"!) ----"Madame Mim" voice Martha Wentwoth played the maid (and made the witch sound VERY much like June Foray as a generic witch/Withc Hazel!!).
THE MECHANICAL BOY (Krofft,1969): HR Pufenstuff (Lennie Weinrib) is so sad in one part that his voice sounds like maligned "Scamltz" crooner Vaughn Mon roe (RACING WITH THE MOON,GHOST RIDES) or Barney Rubble..Goll-eee, can't GOMER PYLE (who his voice no0rmally sounds like) sound sad..
some more WB:
FAGIN'S FRESHMAN (1938) Lionel Stander does the "Fagin:" cat buthalfway through Phil Kramer or Frank Graham take ove.r.
The Warner Three Bears--Billy Bletcher is Pa (& Bea Benadaret Ma and Stan Freberg Junyer) since 1948 (and Bea wasm ama since 1943) but WHAT'S BREWIN' BRUIN [2/21/48] and BEAR FEAT [12/3/49] had Mel Blanc doing a line at the end..first "QUIIIIIETTT!" and "1928!"
THE WINCBLOWN HARE (949): Jim Backus did (Ibeleive it IS him) the first line, "I'll blow your house down" but Mel did the rest of the dialogue..]
THE BIG SNOOZE (1946), THE RABBIT OF SEVILEL (1950) and
WHAT'S OPER DOC ('57), had Blanc pinch-hitting for A.Q.Bryan as Fudd (repsectively.."Agony..Ag-oh-nee","Ouch! Ouch! Ouch!-thus verifying the "s": on the end of MB's voice credit since otherwise only is Mel there, and "SMOGGG"----though BUGS BUNNY ON BROADWAY had Bryan all the wya through on that last one--not to mention STUPID CUPID,1944, and SCARLET PUMPERNICKEL,1950,both Daffy classics,hving mel instead of AQB as Fudd..)
One Unviersal/Lantz Woody short,WHO'S COOKIN/ WHO, I think,form the earl 1940s, had a cat normally with a rapsy roggy voice (by I believe, Danny Webb),tlaking in a different voice in final agreeman with Woody ("Yeaahh!")
And of coruse Bea Benadaret and Blanc in an EGG SCRAMBLE (WB),1950,as prissy, and Bletvher and Blanc as the walrus and wolf in 1939's PORKY's TIRE TROUBLE and 1943's LITTLE RED RIDING RABBIT,repsectively ("firt: "A dog. I....Hate...DAWGGGGGS!" and "He ain't here..he ain't here i either" then "Get outta here" and then some French gibberish)
Finally Fred Flinstone, though voiced not by Henry Corden (RIP) but by Alan Reed (RIP since 1977) regualrly in the 1960s series (the ONLY FLINTSTONES stuff far as I'm concerned),WAS "SUNG" by Mr.Corden severla times..but not in THERE'S NO BZI LIKE SHOW BIZ ("Let the Sunsine in") where to show, post-nightmare, how bad his singing really is, he sings in Alan Reed's voice..(And Bamm bamm makes the square-sign,and he and pebbles giggle..)
Alan Reed singing
H-B's Art Scott told me (in 1984) that Alan Reed "couldn't carry a song in a barrel".
LOL! That's what Mark Evanier (GARFIELD, GROO, many7 posts online and POVOnline,.com,etc.) told me and others ten years ago!
