The absence of Mel Blanc hurt this album tremendously, but the four voice actors who played Bugs Bunny, Daffy Duck, Elmer Fudd and Taz did a pretty decent job. Bugs was played by an actor nemed Mendi Segal (sp?) Daffy was Joe Alaskey, Taz was Jim Cummings, and Fudd was Jim Meskimen, who later wound up doing George W. Bush for the jibjab.com political cartoons.
Here's a sampling of the results...not bad, really! A real highlight is Joe Alaskey doing Yosemite Sam as a pirate in "Help!"...
UPDATE (12/18/07): Bob Bergen sends along some more information about the LT Beatles album:
Regarding your Looney Tunes Beatles blog, I myself participated in this project, but sadly the songs I sang were cut. Originally Porky sang Mother Nature's Son, and Tweety sang Yellow Submarine. But for reasons I don't know they decided to cut Porky and Tweety. I think the feeling was they wanted to have a Looney Tunes fab 4. With the inclusion of Porky and Tweety, that would make 6. Too many toons. Those tracks exist somewhere. Not sure where, though.
I did participate (and thankfully didn't get cut) on Bugs and Friends Sing Elvis. Porky was fat Elvis. It came in a blue suede CD box.
