i was in 3d grade and i remember that song vividly!
If Mama Cass had shared that ham sandwich with Karen Carpenter, they'd both be alive today.
Re nearly nothing: I remember a Leonard Bernstein Young People's concert about that time, during which he selected a few pop songs of the time (or nearly the time) and demonstrated they had actual musical value. One was a Beatles song (I don't remember which one, natch), one was an Association song (Along Comes Mary, of which Lennie, [the old sodomite] seemed quite fond), and Monday, Monday. At least, those were the ones I remember.
