Sorry to bump this thread, but a few of us here over at a pro-Spumco forum, which will go unnamed

; are discussing this very topic and one poster linked to this. I will say, Charles Adler seems to be hated by John K. who then liked Cow and Chicken and others with Mr.Adler's voice..no one mentioned ahosw Mr.K and me don't that much care for as a show CA voiced lead on, Tiny Toons...I know that the name John Kricfalusi, etc. exemplies a man who brings up heated arguments to the point of the fire deparment vehicles coming to exthinguish the internet flames, but I thought four years later after linking to this post to put a few cents in.
What made R&S for me and others was the reivival of a lot of canned music [this also involved records of Raymond Scott only some decades after Warner cartoon orchestras "live"-recorded his stuff..which has a lot in common with the more musical stock themes shared by Hanna-Barbera and Spumco..e.g., Roger Roger, Jack Shaindlin, Phil Green, Van Phillps,etc., not to mention the differently patterned small combo canned stuff R&S borrowed after everyone on television fifty years ago popularized it... FRANKLY Ren and Stimpy reminds me, musical direction-wise, a lot of Bob Clampett's old Beany and Cecil late 50s animated cartoons, what with everything from original songs to canned music to0 reboots of older songs withd iffgerent lyrics to classical music, and R&S, paying tribute to both Clampett and other WB directors, paid additional tribute by, although using recordings, using Ray Scott tunes to boot.]
BTW If you like his work remotely, and you have a "Blogger/Google" account, his former "ALL KINDS of stuff", now known as simply "John K.Stuff", blog, is still around and provides interesting insights to the decline of teleivison Hanna-Barbera, and another pet topic of John K.----character construction,. THe George Liquor designs are hilarious.]
Happy Happy! Joy Joy!
