Yes, that is who it is by.
I wouldn't consider it a generic pop-tune though. It was dark song, and the Mamas and Pappas were attempting to be a rebellious cutting edge folk-rock band, rather than going for slick bubble gum pop sound.
Although the song has become so mainstream, especially with the 101 cover versions, it has become a pop staple.
