"Lentil Nightmare", by Neil.
It seems to me that a parody of a particular genre of music, with the passage of time, becomes indistinguishable from the genre of music that is being parodied, as long as the musicians involved know what it is they are having fun with.
Here is the evidence. (In this example, and this may or may not be important, the genre concerned was already a few years past its moment in the sun when this was made. It's easier, perhaps, not to sound dated when the sounds you are making are, themselves, already dated. No, I don't understand what I'm saying either.)
The fun starts around one and a half minutes in. If you don't know The Young Ones then (a) this may make no sense at all and (b) I feel sorry for you. Don't forget, you are here for the music. And, I suppose, the vocal, uh, "stylings". (Bonus: listen out for the voice of Stephen Fry.)
