Who Bought Rod MuKuen Books?

I wasn’t born in any time to remember Rod McKuen, and I have been trying to figure out why so many people bought his books in the late 1960’s and early 1970’s. They’re remarakbly vapid, and don’t contain very good poetry. Does anyone on this board remember why they were so popular?

As someone said of “Interiors”, Woody Allen’s attempt at doing a Bergmann film:

It was deep on the surface.

My Mom bought them, she was going through a messy divorce from my biological father. She also had some ethno comic guy 'Vern" something or Somthing 'Vern". Something about Hold Me. Same sort of surface deep writing.

Dad’s got a copy of “Listen to the Warm” that I’ve yet to read.

I once bought a copy of LISTEN TO THE WARM–but it was to use as a prop in a play. Object: ridicule. Does that count?
