WFMU's posted MP3s of numerous "answer records," such as the frightening "Dawn of Correction" (a reactionary response to "Eve of Destruction") and Lou Christie's ultra-obscure "Mr. Tenor Man." Interesting stuff:

I remember an answer record called "Big Fat Juan" which was extremely offensive ("that man made of smell") and wondered if it would be included. There was a Cajun Queen single put out too; was it on this list?
there's a difference between an "answer record" and a parody. I'm assuming "Big Fat Juan" was a parody of "Big Bad John"?
My fave is the answer to Shirley Brown's "Woman to Woman" ("Hello, may I speak to Barbara? Barbara, this is Shirley..."), "From His Woman to You", which of course was done by a Barbara, Barbara Mason ("Hello, Shirley...?"). Both made the Top 40 in '74.
